I had just ordered this ball when these three reviews came out.  It was too late to cancel as the ball was being drilled. Naturally I was very concerned.

Talking to my proshop owner, he says he has a Bully with about 100 games on it and, while it has lost some of its hook, which is typical, it still has a strong reaction.  He did say that the ball should be cleaned after each league session and to keep some surface on the ball after each 15 or 20 games.  He uses a gray scotch pad and just lighly (not hard) goes over the surface.  This, of course applies if you want to keep the ball in box condition.

Also, if you'll check my post earlier this month, someone replied that they too had over 100 games on their Bully and it had not lost any of its hook.

I've only thrown the ball one game to test out the fit and I am really impressed.  It has a strong but controllable movement and hits hard.

Like any of the newer equipment, I think maintenance is the key.  

Hopes this helps.
