RE: Helical fletching?
I always shot mechanical broadheads. Recently went with Muzzys. Mechanical always shot the same as field points. When I shot the Muzzy practice blades I was about 12 inches low and 6 inches to the left. I had 4" fletching so I stripped off the fletchings and aligned my broadheads with my new 5" fletchings with a slight offset (don't know how many degrees offset). The were dead on after this. Shooting a 70-lb bow 29" draw and with Game Tracker CX Hunter 300 and 125 gr. 3 bladed Muzzys. The alignment of the broadhead with the fletchings and the longer 5" fletchings is what I believe corrected the problem.
The harder I work, the luckier I get!
