I agree with alot of what Len says. I myself am a bareshaft guy, generally I don't paper tune, I bareshaft. What I have been doing lately is this.

I take every arrow shaft I bought, install nocks, inserts and fletch 3. Then I get the bareshafts and fletched shaftsshooting the same at 30 yards. Then I take and make the 3 fletched shafts bareshafts again. I shoot every arrow into a group at 30 (all bareshafts). If I shank one I go and pull it right away. Any arrows that are out of the group are shot again at another target, if they hit good the next two times I keep them if not they are junked.

Bareshafting and paper tuning tell you the same thing. I like bareshafting because it seems to be more precise. I can have a bow shot a bullet hole at 5 feet, and the bareshaft be off by 8" at 30 yards. I get the bareshaft flying good, go and paper tune and it is still a bullet hole.

My GAURANTEE, If I bareshaft tune a bow, and the broadheads spin true they will fly to the same point out to 50 yards (Never tried further).
