Good to hear critman. If I do the back tension and pause, I am almost guaranteed a kill. It's amazing, huh! Another exercise that is good if you start getting into the habit of not "squeezing" your back tension and try using your arm instead... or if you neglect back tension: Stand with a tree, corner of a building, or a post behind your string arm elbow. As you draw to and anchor, press your string elbow, or just above it against the post, tree, or building corner. Focus on pressing just a tiny amount of pressure against the immovable object as you pause, focus, then release. Your first couple of shots will likely be off a bit as you will be focusing behind you on that elbow... but after a couple of shots you will be amazed at your release and the feeling of back tension. I have to refresh every now and then using this method just to remind me what everything is supposed to feel like. Just a few shots every now and then gives me a tune up.
Hope this helps out,
Rick
