RE: whisker biscuts
I shot the WB with 2" Blazers. They wrinkled and then tore off.
My uncle shot the 4" plastic vanes and they wrinkled and then tore off.
I can purchase a WB for $50 vs. $75 for a drop away.
But when I have to keep re-fletching.....that $25 diff. is going to be spent really quickly!
