DC, I know you have much more experience in this. But I find changing Brace Height does very little for me. I can fine tune things, but thats it.

I first will bare shaft at 30.5" arrow length, and then change points from 125-250. If I find things too weak with 125gr tip, I will cut the arrow 1/2". But I can't go below 29" and really don't want to go below 29.5". Sometimes I might shoot thru paper.

I find tuning the arrow for the bow with bareshaft out to 25 yards best. Then move to broadheads.
