ok guys, I have an autoflex, picked it up used maybe 6 months ago. For me it works really well, gained some yardage and dispersion is better. I did have to try a couple different driver heads, M4 D head worked well distance wise but way too much draw. Picked up a used SIM2 head and it's much better. I messed with the weights to lower the headweight cause everybody said lower is better but that didn't work out so well so I'm back to stock. It's a great combo for me. And @"Tcafla" he plays in a couple of the groups I play in. He first hit my autoflex and was just crushing it so he picked one up. He's just knocking the drives out of sight and straight. So how much is 15 or 20 yards worth assuming the dispersion stays good? For me the price is worth it and for Tcafla it is definitely worth it. I loaned the autoflex to another friend and he ended up buying one also. For some swings and driver combo's it's a winner. But I've had others hit mine and it doesn't work at all for them. It's not a plug and play shaft, takes patience and quite a bit of tinkering to get it right. Will it work for everybody, probably not, actually no way in hell. But no shaft will work for everybody.
