All responses are intelligent, to the extent that you have provided adequate information.
However, without seeing how you are throwing the ball, it is hard to tell what the problem really is. I suggest that you spend the money that you were going to spend on your next ball, on a good coach and a few coaching sessions. It is obvious that you have limited knowledge as to how to "throw a hook" ball, to use your terminology.
No, I am not being a smart arse. Just giving you some sound advice. If you choose not to take it, at least post a video so that the guys on here can see you bowl. You will then get some useful critique from some of the guys on here. Others will give you bs.
Last, I have a Momentum Swing and a Virtual Gravity. While they both react differently on the lane, I could get either to hook in a flood. It sounds to me like your ball speed and rev rate is not matching up, but again, this is just a stab in the dark.
