There is a local pro at our house. He said the Impulse was his most hooking ball, so I asked if I could throw, he had no problem, so I threw it. It is a good hitting ball(every shot was 8 no matter if if was flush or through the nose.), but I couldn't get it to hook anymore then my OI,and i never got a strike with it in 2 games. What i was wanting to know is has anyone elses had this problem.
