If you like the hunting features of the biscuit but want to maximize fps, try-

1- Making sure you have the correctly sized biscuit for your arrow.

2- Trim the backside of the biscuit.

3- Use less helical/offset vanes/feathers.

4- Buy an '04 replacement biscuit, the one with brown/black biscuits.

Many have reported being able to eliminate almost all fps loss and still retain the desireable qualities of the biscuit. No reason you can't too.
