I kept, and may be about to buy some soon, large black pigs. I found them easy to handle, fantastic mothers and they are also a grazing pig so don't do massive amonts of damage to the land, provided they're moved regularly. they also produce awesomely flavoured meat. This is my opinion a word of warning if you keep loucester old spot pigs, they are traditionally an orchard pig and have to have a lot of space, I did read that they can become obese if they don't have a lot of space. Why not buy 3 pigs of the 3 breeds you like and at the end of a year decide which pig you like best.
