I am having a similar issue w/ my Whammy...I am definitely getting contact b/c my arrows no matter how the rest is adjusted or the timing is adjusted keep hitting my right prong.

I can see the extra wear on the teflon and I have tried everything from new arrows to changing center shot incase center shot is off at draw.

I have play w/ spine and I have played with tiller. My cam timing is fine. I am beginning to think it is the rest. I am putting on either my hostage or WB to see if I have similar problems or not. I have even adjusted grip, and tried to torque the bow in various positions just to keep different impact. No luck.

Bowboy let me know the solution to your problem in case I can apply it to myself. Good luck.
