Yes, that caught our attention as well; almost like an immortal pickleball! And to use part of a quote, from the "300" movie, "we will put that to the test". Our take on the Selkirk Pro S1 is that it is a lively ball that spins nicely, and... Well, to be honest, we were not breaking them, so we have to agree with Selkirk's assertion that the Pro S1 is very crack resistant. In addition, the ball performs well and predictably (for a decent period of time). That said, although they are not prone to crack, after maybe ten hours of play, they do lose roundness and at that point, join the pile other broken pickleballs. Officially, Selkirk requires 4 balls to be cracked (not just one), and below is a link leading to their official S1 ball return policy: www.selkirk.com/pages/ballwarranty Mark/ Pickleball Warehouse
I wish that I could offer up some details on a Cheetah pickleball or paddle for that matter. Thus far, Cheetah is a company that prefers to sell direct off their own site. Looking at the M45 ball, and reading the product description Cheetah provides, it appears that it would be a good ball; one piece construction, 40 holes, and what they refer to as a mid-compression ball, for a lively response.

Holy diamonds, 74 cm is my mistake for sure, and would make it a pretty big non-USAPA approved ball! Mahalos for pointing that out, and proves that it takes a village.. Cheers, Mark/TP
Definitely a valid question, considering the Vulcan ball is the official ball for lots of tour level events. We did not, and still do not have any of those balls to test, and is the only reason it was not reviewed. From what I understand, many pro players do not like the way the Vulcan ball plays/ feels. Amidst the gripes about the Vulcan ball, are rumors that another ball is being used in some events, and just feature the Vulcan branding on it. Mark/TP
