There is something else that hasn' t been mentioned that I recall.Release shooter with d-loops shouldn' t have a hard time having the 2 hit real close with just tuning the field points if they are good at tuning.Arrows should be coming out straight or very close to straight.
Finger shooter have way more variable to contend with than the other guys do.They will almost always have more kick than release shooters from their arrows.High left from right handed shooters.This will cause a much different reaction from broadheads than from field points and I believe that this is a case of tuning the broadheads and forgetting the field points.
I don' t shoot fingers except on the ocasional recurve shooting I do but it is usually just for fun and I am not using broadheads.I have done some pheasant and quail hunting with blunts but not broadheads.The tuning their consisted of shooting Mt Dew bottles all over the yard.If I were hunting big game there would be much more tuning.The 5" flu flu' s will take care of almost any kick.
