I would not make it too short but then again not too long. I hope this helps. Actaully you might need a little extra if you will be torquing the head around. It might take a little while to find an anchor point also. I find that I can pull through the shot a little better if I am roatating the release backwards instead of side to side. If I hold my bow hand out and simulate rotating the release pinky inwards my bow hand moves to the side a little and is harder to hold on the mark. If I rotate in a backwards motion I can hold my bowhand on the mark. Keep practicing with the back tension and you wont be sorry.
