RE: D-Loop Problem
Make sure you're loop isn't tied on the same side of the string for both ends which can cause the spinning. If your strings are shot, accessories such as peeps and loops can and will often spin (as much as 90-180 degrees if it's really shot or tied in wrong). My first loop on my CR334 was tied by someone else, and when my string became extremely worn out, my loop would turn almost 90 degrees after every shot. If it's a new string/loop...check to see how it's tied.
