Many people, myself included, have a cleaner release with the deep hook than otherwise. This has limits, however. Too deep a hook and the advantages disappear. It doesn't require that much effort to shoot for a while with the string in different positions, all the way from on the pads to well unto the second joint, to find out where your sweet spot is. It's possible that you will find that you have one position that works better for target shooting with a light draw weight bow and another position that works better for hunting weight bows. You may also find that you need to fine tune finger pressure among the string fingers before you arrive at the best result.
