i know this thread is a little old, but here goes.

i got my 580xd from 3balls.com & it's the longest & straightest driver i've ever hit. i demo'ed with the stock shaft & didn't like it, so when i ordered i got the purple ice shaft and it's an awesome combo.

very easy to turn the ball either way, doesn't look too big at set up, & only cost $170 usd. highly recommend to anyone.
