you should look at the Keeton release then .. it has helped me tremendously ... once set up properly it helps with draw and hold... ..
I'll have to look that up thanks! My release is getting old and if any recall, I had an issue with it not clamping properly a couple of years back. So I know I need to up grade.
it is set up so that there is equal pressure on the strap and the 'metal' handle so to speak when drawing and at full draw/anchor, its like a 4 fingered thumb, but with an index finger trigger ... here is another quick vid with good 'ol Bill Winke ..
