I will be getting a new bow and new arrows this spring and I am probably going to get vanes because thats what the carbond express terminators come with. I was wondering if they have a right wing and left wing. Are all of them offset? I would like to know because my bodoodle rest has a very narrow gap and my feathers hit but it doesn' t effect them. I was wondering if this would effect the vanes flight? Thanks for the help-sam
