I bought a Bowtech Extreme VFT, 28" draw and a couple dozed 2413 Easton shafts and practiced my but off since June and I' m very happy with the results. However, I do question the shaft choice I made. I have experimented with 100 and 125 gr. broadheads and think the 125' s group better. The result is a pretty heavy arrow. Am I missing something obvious by using such a setup?

Thanks for any input!
