I'm wondering if you guys are arguing over different things....
If you're talking ball speed off the hand, 17-18 is average to fast. If that's at the deck, then it's fast since normal friction a 17mph ball would encounter would slow it down to around 15mph. Me thinks Mav is thinking at the deck while the others are thinking off the hand...
EDIT: Considering the original poster says his rpm rate is around 300, I'd guess that his 17-18mph is probably off the hand, because otherwise I'd imagine he has some serious problems getting the ball to turn over as he'd be speed dominant.
