Do arrows with offset or helical fletch begin to rotate immediately upon release? I have heard (on this board) that they don't.

Here is my situation: I am shooting ICS carbons with straight offset fletching through a QuickTune 1000 prong rest. I have about an 8" brace height on my MQ-32. To avoid fletching contact, I have had to rotate the nocks so that when you view the nocked arrow from the rear you would swear that one of the hen vanes and the cock vane would strike the rest. But they don't.

To me, it would seem that my arrow is rotating into a "clear" position as it exits the rest. This is contrary to what I have heard in that the arrow doesn't begin to rotate until it is well clear of the bow.

What else could be happening?
