I have an 2004 Supra....and somthing weird is up. At 60-80 yards and up my groups ar solid.....but from 10-40 yards...my groups are all over the place. I have a 29" draw at 60#.......im shooting 410 Redlines...and it seems that when i bare shaft tune or paper tune it says my arrow is too stiff.......would a stiff arrow do that? And im planing on getting a pair of barnsdale cams.....Ive heard that they go very fast so i might not have to worry about the stiff arrow.....but ive heard that the tri-stars need a arrow thats weaker than its suppose to have. So im not sure wiether to get tri-stars or the wedal cams.
