As always the best way to find out is to ask. So will a helical truly improve your arrow flite in a hunting set up when using fixed broadheads? I use the muzzy zero effect and love it, they suggest using as much of a helical as possible, but I was also told that on fixed heads that the spin may cause the blades to plain and be less accurate and slow down arrow speed. What has been your finding on this? Thanks for the help. (I use muzzy heads).
