I am the minority. I shoot a super fast bow with 80 lbs. My bow is tuned properly, but I'll be damned if I can get a fixed blade to group consistant.I think it's just the speed of the arrow.
My NAP Shockwaves do great and I can easly take a Turkey head off at20 yards and have always been complete pass throughs on Deer. If you look at the pic here you are looking at the exit wound through the shoulder. Shot was about 25 yards. Was able to remove the arrow and broadhead from a branch, resharpen and reuse again.
They work for me.
