Well I've been saying all along the whisker biscuit is the only way to go. I just put a Muzzy Zero Effect on my Switchback and man is it nice. I had to do a little fine tuning (hitting my thumb area mostly) but now that's it's tuned, I'm kinda liking it. I have nothing bad to say about the biscuit other than it's hard on my vanes on my arrows after awhile. I put mole skin on the Muzzy hook and on the shelf of the bow to eliminate any unwanted noise. Any of you have the Zero Effect? Tell me what you think.
