RE: Whisker Biscuit Problem
If you use a stiff vane and glue it with goat tuff and put an extra drop on the front of each vane, you will have no trouble with them coming off.
By the way, I have to dissagree with ewolf. You cannot obtain better arrow flight by switching to another rest. Arrow flight is a function of correct tuning and proper spine. There are thousands of WB users, getting perfect flight. It can happen by accident, but works best on any rest, if you know what you're doing.
