All of mine were frim kc stuff and graffted,i produced grafters to and won loads of terrier shows with them.never been to a kc show,but to me its how you bring them up as alot of people think they are slow starters so they leave them in until they are 3.treat them like ya russels,lakelands and blackuns and they will graft like them or better.now they are at least £500 a pup if i was going to get another now i would be looking at a good quality 1 for that sort of cash and every dig i was on from that been 6mths old it would be with me watching and listerning till its time come.
