I'm a fixed blade guy too. I have heard too many horror stories about Mech. I know, they work a lot of the time, but I WILL NOT have my shot of a lifetime come down to moving blades, rubber bands, etc.
Kirby - Try Slick Trick broadheads, they seem to fly VERY well! I've shot them out to 60 yards and they group great. Not to state the obvious, but make sure you bow is tuned, almost all b-heads should fly well if it is.
