MM tamworths are lovely, highly intelligent, vocal, fun the kids would love them. We kept tamworths for years, and would do again, but for age and arthritis.
GOS are lovely, docile and easy to manage (not that tamworths aren't they are just the racehorse of the pig world). Large blacks for a stronger tasting meat.
Never tried OSB pigs, (I dont think there are any in N. France although if anyone knows of any please let me know.)
