Well I just can' t get them to fly with any consistancy. They' re good then bad then good again then bad again. I have tried 4" right helical and left helical, 5" right helical, re-paper tuned my bow, checked for vane clearance, the whole nine yards. I' m shooting touching groups at 25 yards and had to refletch my arrows cause I kept tearing vanes with field tips. I got them hitting within one inch of my field tips at the pro shop but got home and shot the next day and the first round was great then the second round was crap. I just don' t have the confidence in these heads that I need and want to hunt with them. They' re real dang noisy too and that bugs the heck out of me.

Think I' m going to give Muzzies and Inner Locks a try.
