When bare shaft tunning what is the consensous on cresting or wraping the arrow before doing this?  :cool:

Definitely! Cresting and arrow wraps add weight to the back of the arrow that effect it's dynamic spine. Comparing bareshafts with and without cresting or wraps...the archer will see that the bareshaft with the cresting or wrap will respond stiffer than one without.

Ditto on BW's comment.  I see the same.  TgE
