Jeff, I had worries of things like that happening with the Whammy. It's a great concept, I just couldn't get it out my head that it could very easily come out of whack. The timing was very critical on that rest. Not so much with the Limb Driver.
I've actually played with fletch configurations on the Limb Driver and no matter how I oriented the fletching, I was getting clearence. Good enough for me.
