What about a Berkshire ? Apparently it makes a nice cross, not tried it myself......yet

I know of someone who has a Tamworth sow that crosses with a KK boar and she rears the piglets for pork.
The only pigs I have which don't get on with the Kunes are OSB's - (Large Blacks, Berkshire, Tamworths - all fine) but that could just be a personality clash

Anything would work really - just pick something you like the look of
