I shoot a bear grizzly recurve, 55#@28 but I have a 30 inch draw. I'm shooting easton 2219 with 125 grain tips. I have four inch parabolic truflight feathers. I have been shooting a lot lately and my arrows seem to have started kicking to the left. I know it's not a spine problem because they are bareshaft tuned and squared off so I know it's not my arrows so the only other place to look is my form. Any idea of what may cause this? Thanks.
