The D ring will make your shots inconsistent!
You' ll be left, then right, then left, and so on. The weight at the very last movement of the string on the shot wants to swivel the D-ring around to the front. While the nock is still attached to the string. Left, right, left, right. Seriously.
Took me a couple of weeks to figure it out. Took it off and an immediate bull/robinhood.
