Well I got a Whisker Biscuit put on my bow last season, and it seemed to not be shooting the same as my previous rest. The guy that put it on said he squared it up and put it on, so I figured it should be alright. I didn't end up shooting a deer last season with my bow, and I shot my Muzzys a couple times and they seemed to be shooting alright. I didn't shoot them a whole lot, but enough to get the feel for them. I took the broadhead off, and let my brother shoot the same broadhead on his arrow, and his shot straight. He has a brand new bow this year.
