I have the Drop Tine version of the Biscuit on my Justice. I am shooting 4" feathers with a 6 degree helical. The feathers all sustain some damage over time, but the one at the 4 o'clock position is the worst. My theory is that since the other two feathers are on either side of the opening where you load the arrow, there is more give to the fibers where those feathers pass through. The feather at 4 o'clock is about opposite the opening, where the fibers would have the least give as the fletching passes through.

I was wondering if it is typical for the vane in this position to also take more damage.

I am thinking of trying some vanes. The CAP website recommends the Bohnings and also Flex Fletch. Some people on this site rave about the Bohning Blazers also.
