Oneball61, I have 2 of the original Muzzy's (one on a Parker and one on a Bowtech) and the one for the Outback roller cam. They are very good rests but induce a small amount of hand shock at the shot. Not a lot but enough to be a concern. I am trying the buscuit due to all the good things I've heard on this forum and from people I know and due to my nature to tinker more than I should sometimes[&:]. Len in Maryland, Could you give a little input on how to reconize a 'false' tune and how you 'properly' tune the buscuit. Don
