blazer helical?
 

What degree helical will flybetter out of a whisker biscuit rest a 6 degree or a 1 degree?

With the WB, lots of people straight fletch or just a slight offset, anything to reduce the amount of drag through those bristles. I shoot as much helical as I can get on mine, but with a drop-away. I would roll with the 1 degree if I were you.
