I just recently bought new arrows and changed what I was shooting. I shoot Easton's because I have always had really good performance out of them. I was shooting Carbon Epic C2 400's, now I shoot Epic ST 400's. I shoot with a 3 pin PSE Top Gun sight, with the C2's the top pin was good to almost 25 yards, second pin got me out to around 40 yards, and the bottom pin was good to almost 60 yards. Now I am shooting off of the bottom pin and having to aim a little high to hit bullseyes at 25 yards. My local bow shop tells me that if I switch over to an 85 grain set up instead of the 100 grain set up that I currently use on field points and broadheads that everything will probably go back to where it was when I was shooting the C2's. Will I loose a lot of energy doing that though? Would I be better off just readjusting everything and sticking to the 100 grain set up?:usa:
