RE: whisker bisquit?
I personally do not care for the whisker biscuit rest. It does not allow the proper "archer's paradox" to happen. But with most people shooting releases the arrow does not bend as much as it does when shooting with fingers.
I did buy a whisker biscuit for around $40 and tested it, even switching back and forth with my old faithful star hunter and my arrow groups were not as tight with it. Have not touched it again, another $40 down the drain, LOL. Not sure what the general consensus is as I have not read all the old posts, but I figured I would offer my test results.
