Played our state games last weekend.
Our club uses the DHS D40+ ball normally. But because some players want to train for USATT events (which has 3 sponsored balls - Butterly, Nittaku, Joola) they want to use the Nittaku ball. That's fine. Tournament went well and was successful.
But wow do I not like this ball. I won't even get that much into price (48 balls - $138. No Joke). Price aside, the DHS D40+ ball is flat out surperior in really every way. Or that ways that matter.
Durability:
No doubt the Nittaku ball is absolutely more firm that the DHS ball. My training partner hit the ball just long off the table. Not all that fast. Bounced once on the floor and then hit the wall. Crack... The Nittaku ball is simply more prone to brakes because it doesn't flex. The DHS ball on contrast I can't recall breaking from a player's hit. Generally if one brakes, that's because someone accidentally stepped on it.
Spin:
This can be subjective but I think the DHS ball spins better as well. When you think about the physics, it makes sense to me. When you hit the ball, the DHS ball will technically conform more as it flexes thus more of your racket grabs it. Firthermore, when say topspinning out, if the ball baloons out (even if by .01%), it can spin faster than a perfectly round ball. Again probably talking the most minor of details but that was my impression. The Nittaku ball doesn't spin as well.
So in to conclude. We had a ball that was roughtly 5 times more expensive, was more brittle, and didn't spin as well.... Yeah.
