Feather's are very forgiving compared to vanes so you can use just about any rest you like.That said you should still align your nock's to give the best clearance possible.Just cut off the feathers but leave the quill.Mark the contact point(s) on the rest with lipstick and shoot it.See where the lipstick marked the arrow.Just keep rotating the nock until there is no lipstick rubbing off the rest onto the quill.
