Franklin X-40 vs Dura Fast 40 vs Selkirk Pro S1: Which to Buy

If you play outdoors and want the ball most of the country plays, buy the Franklin X-40. If you play in a group that hits hard, plays fast and does not mind buying balls often, buy the Dura Fast 40. If you play through a Northeast autumn and are sick of cracked balls, buy the Selkirk Pro S1 and register the warranty. If you want the ball the PPA and MLP pros are using this season, that is none of the three — it is the Life Time LT Pro 48, and it comes with a catch we get to below. Skip the Vulcan VPRO Flight; its moment has passed.

We have not played these balls side by side in any controlled way, and this is not a first-hand test. What follows synthesizes published testing from Pickleball Effect, Pickleheads, The Dink and PickleballMAX, checked against the manufacturers’ own spec sheets and the USA Pickleball equipment standard. Where sources disagree we say so. Our method is on how we evaluate gear.

The spec every one of these balls has to hit

Before the marketing, the rule. USA Pickleball’s Equipment Standards Manual (revision 3.0, January 2025, section 2.D) requires a ball between 2.87 and 2.97 inches in diameter, weighing 0.78 to 0.935 ounces, with 26 to 40 circular holes, that rebounds 30 to 34 inches to the top of the ball when dropped from 78 inches onto a granite plate at 70°F. Hardness (40–50 on the Shore D scale) is still recorded but is no longer a compliance requirement. A slight ridge at a seam is allowed as long as it does not affect flight.

That window is wide enough that three balls can all be legal and play nothing alike: the Dura at the hard, fast, high-bounce end, the X-40 in the middle, the Pro S1 slightly heavier and thicker-walled. The differences you feel on court live inside the tolerance.

All four of the main balls here are on the USA Pickleball approved ball list: the Franklin X-40 (listed in several colours), the Dura Fast 40 (listed under Pickleball Inc.), the Selkirk Pro S1 and the Vulcan VPRO Flight Outdoor. The LT Pro 48 is not, and cannot be as the rule is written, because it has 48 holes.

Comparison table

Figures are from each brand’s product page, with the Dura hole breakdown and the LT Pro 48 bounce (33.5 inches from 78 inches onto concrete) from Pickleball Central. Prices are at time of writing and move with sales. Selkirk’s published 2.8 inches sits below the 2.87-inch USAP floor as printed; we take that as rounding, since the Pro S1 is on the approved list.

Who actually uses what in 2026

The PPA Tour named the LT Pro 48 its official ball on 1 August 2025. Major League Pickleball followed on 29 April 2026, ahead of the season opener in Dallas. Both had used the Vulcan VPRO Flight before that: the PPA from January 2024, per the tour’s own ball guide, and MLP from July 2024. Vulcan’s product page still says “Official Ball of the PPA Tour and Major League Pickleball.” It is not.

The APP Tour has been a Franklin X-40 tour since a multi-year extension announced in March 2024, covering APP Tour and Next Gen events. Franklin also holds the US Open Pickleball Championships. The Dura Fast 40, per Pickleball Central, was for many years the ball of the USA Pickleball National Championships, and Onix currently bills it as the official ball of the Senior Pro Tour.

So if you are asking “what do the pros play?” the answer in 2026 is a 48-hole two-piece ball that USA Pickleball does not approve, at the two biggest properties, and the X-40 at the third. That should shape how you read tour endorsements: the tours pick balls on a contract and on how they play on acrylic under lights, not on what your local sanctioned tournament will hand you.

Franklin X-40 — the default, and still the right default for most people

Franklin describes the X-40 as one-piece, rotationally moulded polyethylene with 40 machine-drilled holes, at 26 grams and 74 mm. It is the ball you will find at more public courts than any other, which The Dink calls “the most common best pickleball ball found in recreational and tournament play,” and that ubiquity is a real feature: your practice ball and your tournament ball are the same object.

On durability the testers roughly agree. Pickleheads puts it at 20 to 30 games and says it holds up above 40°F. Pickleball Effect, in its April 2026 ranking, rates its durability “slightly above average” and names it the best slower outdoor ball, while noting it softens more than most above 90°F. FORWRD’s July 2026 review gives 15–25 sessions on rough concrete and 35–50 on smooth sealed courts, and reports cracking roughly doubling below 50°F. That cold-weather weakness is the X-40’s one consistent knock, and it is the reason we wrote a separate piece on why pickleballs crack in the cold.

On pace, the X-40 is the slow one of the group. PickleballMAX’s drop test, run by an engineer from 78 inches at four temperatures, found the Dura bounced about an inch higher than the X-40 at every temperature. Pickleheads’ Pro S1 review places the S1 quicker than the X-40 too. If your group’s rallies are long and you like a ball that sits up for a drop, that is a point in the Franklin’s favour, not against it.

Buy this if you play in tournaments or open play and want the ball you will meet there. Don’t buy this if you play through winter in a cold climate and hate buying balls; below about 40°F this is the ball most likely to split.

Dura Fast 40 — fastest, hardest, and the one that cracks

The Dura is the original outdoor ball. Onix describes it as a one-piece, roto-moulded hollow ball with a patented 40-hole layout of large and small holes; Pickleball Central’s listing gives the breakdown as 16 holes at 0.335 inches and 24 at 0.270, a weight of 0.881 ounces and a 32-inch bounce from 75 inches on concrete. It is the lightest and, by every account we found, the fastest ball here.

The Dink calls it “considered by many to be the most durable and fastest-playing ball on the market” and, in the same breath, says the common issue is cracking over time. Those two statements are not a contradiction: the Dura holds its shape and pace right up until it fails, then fails all at once, usually along a hole. Pickleball Effect groups it with the S1 and the Vulcan as balls that “can feel good early on, but they don’t maintain their shape nearly as well as the LT-48 or X-40,” which is the one place the testers split: The Dink’s readers treat the Dura as the durable ball, Pickleball Effect’s bench does not. Our read is that both are describing a hard compound — it resists going out of round, and it cracks.

Cold makes it worse. NYC Pickleball’s blog says you will be “hard-pressed to get through more than a few games with a Dura” below 45°F, and Pickle Geeks says the same thing, same threshold. FORWRD, oddly, credits it with better cold-weather crack durability than the X-40 because of the harder plastic. That is the minority view and we would not bank on it.

Price per ball is the Dura’s quiet advantage: Onix’s 100-pack is $299.99, $3 a ball, and The Dink reports bulk sale pricing around $1. A club buying by the case can treat Duras as consumable.

Buy this if your group plays fast, hard and in warm weather, and you want the ball that rewards a clean paddle. Don’t buy this if you are a rec player buying four at a time. You will pay Franklin money for a ball that dies sooner.

Selkirk Pro S1 — the crack-resistant one, with a shape caveat

Selkirk built the Pro S1 around two ideas: a seamless rotomoulded shell and a patented 38-hole pattern with holes of varying sizes, which the brand says gives consistent flight regardless of spin or angle. It weighs 0.93 ounces, the heaviest here and close to the 0.935-ounce USAP ceiling. Then came the thing that made its reputation: a one-year no-crack warranty.

The cold-weather evidence is consistent across every independent source we found. Pickleheads says it “can withstand 30° sessions without any issues” and scores its durability 10 out of 10 in the group guide, 9.5 in the standalone review. FORWRD’s May 2026 review played it at 38–42°F alongside X-40s and reports three cracked Franklins across two sessions against zero cracked S1s, and zero cracks in 40-plus sessions overall. The NYC Pickleball blog reports not cracking one below 35°F. Pickleheads’ reviewer attributes it to thicker walls than the X-40.

Now the caveat, which Selkirk’s warranty page quietly confirms. Pickleheads found “some of mine lost shape” after a few sessions, producing inconsistent bounces, and Pickleball Effect lists the S1 among the balls that do not hold shape as well as the X-40. The warranty covers “noticeable cracks” only, explicitly excludes balls that have gone out of round, needs a minimum of four defective balls and a receipt, charges a $6 processing fee per claim, and does not cover balls bought at a discount or for clubs and events. So the ball that will not crack may still need replacing; it just fails in the way the warranty does not pay for.

On pace it sits between the other two, quicker than the X-40 and slower than the Dura per Pickleheads. Selkirk lists a 4-pack at $15, on sale at $10, and Pickleball Central has the same pack at $9.99, which puts it at or below Franklin money in small packs. FORWRD’s claim that it costs roughly twice an X-40 per ball does not match current listings.

Buy this if you play outdoors from October to April anywhere with real winters, and you buy at retail so the warranty is live. Don’t buy this if an out-of-round ball bothers you more than a cracked one, or you play indoors: Pickleheads did not like it on wood.

Life Time LT Pro 48 — the pro ball you cannot use in a sanctioned event

The fourth ball belongs here because it is what the PPA and MLP are playing, and because Pickleball Effect’s 2026 ranking puts it first among fast outdoor balls, ahead of everything above. Pickleball Central lists it as injection-moulded, two-piece, 48 holes with chamfered edges (which Life Time says is where cracks start on a conventional ball), 26 grams, 2.9 inches, with a 33.5-inch bounce from 78 inches. Pickleball Effect says it holds its shape and lasts longer than the X-40, and picks it as the best outdoor fast ball.

Two things stop us recommending it as a first ball. It is the only ball here with a seam, and a two-piece shell is exactly the construction USA Pickleball’s rule tolerates rather than prefers. More importantly, 48 holes puts it outside the 26–40 range in section 2.D, and it does not appear on the approved ball list. If your tournament is USAP-sanctioned, this is not your ball. Pickleball Central’s $39.99 12-pack is around $3.33 a ball, X-40 money.

Buy this if you play at a Life Time club or want to practise with the PPA ball. Don’t buy this if you need USA Pickleball approval, which every sanctioned amateur event does.

The one we’d skip: Vulcan VPRO Flight

The VPRO Flight had 18 months as the PPA and MLP ball and never won over the people playing it. The Dink’s July 2024 report on the MLP deal notes the Johns brothers’ frustration that earlier versions “fell out of round quickly and caused inconsistent bounces,” and The Dink’s buying guide still describes mixed reviews, slower hand battles and higher-bouncing drops. Pickleheads gives it 10 to 20 games at $2.40–$3.99 a ball, the shortest life and among the highest prices here, and Pickleball Effect lists it among the balls that lose shape. Both tours have since moved on. It is still USAP approved and Vulcan’s 40-hole, 0.92-ounce spec is fine on paper; there is just no reason to pick it over an X-40 at the same money.

How to choose, in one pass

Start with where you play. Sanctioned tournaments and most open play: X-40, because it is what you will meet. Cold climate, outdoor, October through April: Pro S1, bought at retail, warranty registered, and accept some shape loss. Fast, hard-hitting warm-weather group buying by the case: Dura. Life Time member or PPA obsessive: LT Pro 48, with the approval caveat. Then buy in twelves, not threes; every brand’s per-ball price drops sharply at 12 and again at 36 or 100.

Two more things before you order. A ball can be dead without being cracked — our guide to how long pickleballs last covers the bounce check. And if what you want is a quiet ball, an indoor ball or the cheapest legal ball for a beginner set, none of these is the answer; see our broader indoor, outdoor, quiet and cheap ball roundup instead. For paddle certification, which is a much more active battleground than balls right now, our 2026 certification guide explains why there are two approved lists.
