I recently switched back to aluminum arrows, Easton XX75 2117. I was shooting Gold Tip Trads for a few years. With the Gold Tips I was paper tuned perfect with 5" RW on a 29.5" arrow. I swithed to the aluminum arrows and did some paper shooting with 5" RW, tail high. I also took some shots from 25 yards, man you could see them fly bad. So I fletched some 4" RW and started over. Shooting bullet holes in paper and they fly great, shot some from 30 yards to watch arrow flight.
I do not have a chrono, nor am I gonna buy one anytime soon. I am getting better penetration in the target with the aluminum vs. the carbon.
I am looking forward to getting this set up out to the 3d course sunday with the guys.
BTW, I am shooting 125gr field points and broadheads.
Thanks for the info and let us know how the 3d shoot goes with em...
