CG:
The arrows I am using are ICS size carbons and ACC' s. I did experiment by putting an arrow in the rest when the rest was off the bow. I can shake it around a good bit and it stays in the center. After doing that, I think the problem may be that I have a short bow (34" ) and am connecting the release to the string below the nock. Maybe this is putting too much downward force on the arrow. I could probably try a sting loop, but I would need another release, as I have tried to use a loop with my Winn C 10, and it is too much trouble, IMO. I did put a centerest flipper on the bow when I took the biscuit off, and it is stacking arrows impressively out to 30 yards, so I might go back to that rest with one of my homemade arrow holding devices. I will probably try the cut-out biscuit on my Darton Viper, since it is 43" ata, and seems to shoot great with any rest.
