I'm a big proponent of the Whisker Biscuit so I will chime in here. I feel it's a great hunting/all around rest. It's plenty accurate for 99% of the people reading this, and in the right hands is just as accurate as any other rest on the market today. It's full proof ie: no moving parts to break or go out of tune.
It's key that you set it upright and that starts with the correct size opening. For the most part if you are shooting a stardard carbon arrow youshould be using the
large opening biscuit. Next you should tune your bow. Start off with a true center shot (to your string)a 90deg. arrow nock, even tiller and go from there.
I shoot the standard el-cheapo 4in vanes with no sign of wear and no noise at all. I'm not doing anything special nor am I some "expert tuner" so anybody can get these results.
As far as the whole "Biscuit shooters need to have better form" is just not true. You all must remember that no matter what kind of rest you choose, drop away, prong, biscuit, etc... the arrow is STILL attached to the string and poor form will effect arrow flight. It's not untilthe arrowleaves the string that it's truely "on it's own".
As a hunter I feel there is nothing on the market better, it just does it's job plain and simple. Nothing special about it, no cool levers or pull strings, no adjustable springs or settings. No need to add additionalgizmos to the rest to get it to capture your arrow. (God knows those little glue on arrow holders never come off, especiallyin the rain.....at the wrong time

)
Just put it on, tune it and forget about it......go hunt.
