Dc, supposdly a deep hook relaxs the back of your hand, the further you go towards the tips put more tension or strain in your hand. If you ever shot a release you can seem to pull more because you are pulling with your wrist , kinda the same feeling with the deep hook, hand feels stronger and relaxed so you are supposed to get a cleaner release. I have tried both and now kinda favor the first joint close to the tip. Bob
