Adams:Remove the biscuit from the windage bar. Lay sissors flat on the bowstring side of the biscuit and lift and snip 4-5 bristles at a time working evenly around the circumfrence of the biscuit till you can look at the biscuit edgewise and the bowstring side of the biscuit is flat. On a tuned bow the biscuit loses less than 1% of the arrowspeed with 4" straight fletch. A trimmed biscuit will lose about 1/2% of the arrowspeed with 4" straight fletch. Good luck hunting!
