Pigslayer ,
I just went through this with my inner right vane. I thought it was the cables , so I rotatedthe cable slide out a little. Still getting black on my vanes so on went the lipstick. Came to see the vane was touching bisquit frame because the Bisquit was rear up , front down a little. Evened it out and no more black rubbings

Just shot off my first knock last night

Arrow nocks that is
