One other thing I forgot to mention. When in a tree and when preparing for a shot, I try to brace myself somehow. It keeps you from shaking and if you get a little nervous you can steady yourself. One way I do it is to always stick my butt out and brace it against the tree. This stabilizes you, reduces shaking and also makes you bend at the waist. I also brace against the seat if I have one. I also use a bow holster that I keep the bow in until I'm ready to draw. Takes the strain off the arms and reduces nervousness.
