I consider myself a "snap" shooting and I come to anchor every time. I draw my middle finger to the corner of my mouth, and continue till my thumb goes behind my jaw bone and release. No holding for a split second or anything, my thumb sides behind my jaw and the shot happens. I found this to work for me because when I would stop for a second or two my focus would wonder. Whatever you do, I would recommend doing it on a blind bale for a week or two and then start close and work your way back. Like Stumpkiller said, what works for me may not work for you. Find what works and stick with it.
