Mouse,

There could be two scenerio's that may be happening.

First, it is impossible for the arrow to start turning as long as the nock is still on the string. You have a relative long brace height (which I feel is a good thing). So, after the arrow has left the string, it is able to start turning. It may actually start turning for you before it leave the arrow rest.

Second, there may be a slight amount of torquing taking place. As long as it is kept constant, it is OK.

A solution to your problem may be a fall away rest. That is what I have went to. It is a Golden Key Premier Fall Away. This totally eliminates any clearence problems.

Hope that helps.
