I just bought the 4 finger to try out the other day. I haven't had much time to shoot with it so far. If you draw over about 60#, I'd probably go with the 4 finger so as to have more "power" to draw your bow with. Otherwise, I'd probably do the 3 finger model. So far the biggest thing I DON'T like about it it the fixed head. It would be much better for me if it had a swivel head as I perfer to hold my back tension release in the vertical position. This probably won't be a problem if you have a string loop.
