Path,
I seldom save the hides, but if you want to do it the old way scalding is the best. We used a stock tank filled 2/3 with water set up on cement blocks; a wood fire underneath brings the water to a boil; and we were lazy ... we used the loader to lower the dead pig in. The nice part of the loader is that we never unhooked the hind leg chains; and after the scalding we just lifted it back out, scraped the hair off the hide, gutted, skinned and moved on to the final products.
If you are looking to raise your own, I like a Duroc/Hampshire cross. They are good old breeds that do well in all conditions, grow well, and provide a moist and flavorful meat unlike the modern white breeds. I really prefer to stay more on the Duroc side for their calmness, but there is nothing like a good wild Hamp to get your attention in the middle of the night.
Above all, when you are raising or purchasing your meat you need to remember that "Fat is flavor!"
