We've grown Yorkshires without sunburn issues, and were quite satisfied with their performance. We've also grown the so-called "Blue Butts" and they did well, too, but with vastly less fat than the former breed and that was a huge disappointment to me. The pork was excellent, though, and I wouldn't hesitate to bring another one in if it was offered to me.
A lot of people in East Texas like growing the Red Wattle breed. It's a red-haired heirloom hog. We grew a few of them some years ago and they did very well for us. They are expensive, though, and can be difficult to find, but I think you should really consider looking into them.
