We've had GOS, Saddlebacks and last year OSB. Feeding them lots of windfall apples and plums for a fortnight before their one-way trip to the abattoir is a wonderful idea, the meat and bacon is great. I think the OSBs were the tastiest. On feeding, I used to observe the pound a day up to six months, but that produced incredible (and expensive) amounts of back fat. Last year I stopped at 5 a day. Better, but still 20cm. This year going for Saddleback/Large white cross, hoping the LW will temper the fattiness.
