A deep hook doesn't seem like it would give you a better release, but in my opinion (and according to many top 3-D shooters) it does. It will give you more control and better consistency. I used to shoot with the string as close as I could get it to the tips of my fingers--I also had major release problems, even shooting 82# on a longbow. I went to a deep hook (first joint) and it helps a whole lot. One thing to remember is you have to just relax your hand and let the string shove your fingers out of the way--nobody is fast enough to move their fingers away from the string, and trying to do that will cause you to pluck.
