OK...my old bow I had a pin for 10, 20 and 30 yards. I just baught a new Vectrix XL 30" draw 70# 400g arrow 284fps. Will this theory of having one pin from 10 to 30 yards work for me. I just got my sight in yeasterday and plaied with it a little lastnight. I set my 20 yard pin and then went to 10yrds and shot either high or low can't remember now. Most of my shots are under 20 yards. But that was with my old bow. So, my question is should I set my top pin at 30 yards and be right on at 20 and 10 with it?
