Well about a week ago I got new arrows, I was shooting 5575 GoldTips, now I am shooting Easton Axis 340 with Blazer's took me about 15 min. to get it dialed in...shot a group of 3 arrows the size of Skoal can at 50 yards...SUCKED it up at 40, all over the place....30 and 20 were cake walks....the 40 yard pin has me thinking though...all my other pins are either red or green, my 40 is yellow, and I can't seem to pick it up very well. Do you guys think that is the problem? Do any of you prefer the yellow pins?
