RE: Whisker Biscuit inaccuracy!
Unless your form is perfect or at least very very consistent, no tork, good follow through etc., the whisker biscuit will magnify any problems you might have. This happens because the arrow is in contact with the wb for the entire length of the arrow. Any slight movement before the arrow clears the rest will affect its trajectory. With a drop away, once you let the string go, the arrow is on its way unimpeded. I shot a wb for years and loved it, but once I switched to a drop away my groupstightened big time and that was that.
