Most of the forms I looked at were from Mckenzie. I will say that the guy we use claims that all of the deer he does requires the largest forms possible. He says that Indiana deer have necks that are so big even the 4points need extra large forms. He has done several from Kentuck, Missouri and Tennessee and says that even large rack deer down there don't require the large forms Indiana deer do. Just what he says. He does about 125 mounts annually, so I guess I beleieve him. Would the extra large forms cost more?? I don't know.
