I don't think they ever have a good shape.shoulders and legs are flat and there usually fat but then its only amateur/hobby farmers that keep them.the meat would be good i'm sure.you don't know til you try.rare breeds that finish well i thought were o.s.b,duroc,saddlebacks and g.o.s
As for the hair the ones we done always came out good.those,tamworths and iron age are the best pigs for that even the boar's but they don't finish well either.g.o.s are the worse for hair removal.f**k knows why.
