I have a Tru Ball release that I like using, but I have issues with consistency. I anchor at the same point each time (right below my earlobe), but it seems that some of my releases are jerky. I tried varying the position of my wrist, and the tightness of the strap around my wrist, and it seems to work best if the release strap is a little loose, allowing the strap to rest on the palm of my right hand at full draw. However, when I squeeze the trigger, sometimes the flexion of my finger pulls the string away from my anchor point and the arrow flies to the left. I am getting frustrated!! Some days I can shoot an awesome group, and some days my arrows are all over the place. Anyone have some tips about the correct way to use this release? I need to figure out the problem.
