Mac what sets you make , make sure that the bvr are on drowners to put bvr completely underwater, deep if possible... Also if you have to use bodygrips , put them on a slider if possible if by deep water. Dont stake body grip solid so bvr can take bodygrip underwater and down slider if possible.... Hopefully with this type of setup , any bvr you get wont get bit up anymore than from what fights they already have had...good luck.....
