Pendulum sights work. You just draw back and put the pin on him, and hit the release. It is just one less thing to think about at the moment of truth.
I never could get used to shooting pins. I allowed for everything except making the shot simple. I went to an Eliminator sight on my Oneida Eagle and piled deer up like cord wood in the early 80's and later. A fast bow and a pendulum sight were just what I needed. I have since gone to a crossbow and haven't shot but 2 deer in ten years with it.
