A ton of rec players use Costco Penn's and these are definitely better than those IMO.Definitely a ball that seems good enough for recreational players.
Not seen big wrinkles in any of the balls I've used nor funny bounces. I think the felt is the limiting factor but it moves them from play balls to serve practice balls once the felt is dead.I absolutely hate these balls. The hard rubber that is used makes touch and feel shots more difficult and often the balls don't bounce but skid through the court. The seams on the Triniti balls are very inconsistent and you often see big wrinkles in the felt and if the ball happens to land on one of those wrinkles you get a bad bounce. The felt also seems to wear off pretty quickly in my experience and while they still bounce due to the hard rubber controlling them gets more difficult as they wear. Nice try but needs a lot more work.
