Large Blacks are nice even-tempered pigs, and taste
good 
Not as shapely as OSBs or Saddlebacks (less eye in the bacon) but
really good flavour.
I've never fed any of my pigs more than 5lb per day, even if they weren't getting much in the way of fruit and veg. I do the pound-per-month-of-age thing up to 4lb, then go by condition. If I lose sight of the flank muscle, I cut the nuts back until I can see it again

If you have the right setup, a couple of weaners really isn't that much work. Just make sure you teach them some manners while they're little, though

. (Or buy from a good breeder like Happy Hippy, who will have socialised them and taught them manners before they come to you.
