i too heard of both ways to shoot. and the ole faithful "pull the trigger" method.
i find by coming to full draw and hooking my trigger finger around the trigger, i can trigger the release by squeezing my shoulders together...and i shoot more accurately like that. learned to do that by shooting longer ranges...shrunk my groups alot. now i just gotta become more consistant at it...
shooting close range and eyes closed really helps. i did that for a while, while my bow was all out of whack and i was waitin on a new string to get er back in tune. that week i worked soley on form and release. sometimes 15yds shooting spots working on both eyes opened and follow through...sometimes shooting at a couple feet, eyes closed. taught myself alot that week

and shot better now than i did before..
