Easton's tuning guide doesn't have anything to do with the WB. It is used to help you tune your bow to shoot your arrows with as good of flight as possible. This is of major help to accuracy and penetration problems.

Your bow should be tuned no matter what rest you have on there.

The thing about the WB is though that when it is not in tune it will mark up your vanes like I showed..........this is actually a GOOD thing because if you have a WB that is shredding vanes you know something is not right..........get it adjusted right and you will see that your vanes stay as good as new.
