I actually have bowled in two PBA leagues. Two different houses. As far as hook is concerned, one of the centers allowed me too hook anything but plastic 10 boards at least. On every pattern. The only time I needed a strong ball was once on the Shark in the other center, and I used my Rival. I bet the Bounty Hunter is much stronger. I really haven't bowled on what could be considered heavy oil, except for probably one or two times not including that time on the Shark.
