The problem with high let off bows and fingers is the tendency to twist the string. I shoot fingers, and you have to make sure your hand is flat and aligned with the string. My hand is plastered against the side of my face when I shoot. I also drop off two fingers and hold with just my "bird shooting finger". I use a whisker biscuit for the rest.

By the way....I did try a release once. After I cleaned the blood off my nose from it somehow accidentily going off during the draw, I put the release in a box and haven't looked at it since. I prefer the feel of the string in my hand.
