Just out of curiosity, what is your bowling style (stroker, tweener, cranker) Also, is the 17mph at the pins or at your release?
Reason, is that if you are a stroker, you should go with something like a Reign or 920A (higher end). If you are more a tweener or cranker, you may want to go with something more mid performance that still has a strong cover (Rattler, Python, LaneBreaker, 715A). Another consideration is the Freeze which has a high end cover that people say is stronger than they thought and strong off the dry but is well below high end cost.
