Jim I will definitely try to see him if ever in the neighborhood. I love that stuff. 

Nathan, graft stock works best if you stay apple to apple, orange to orange. like that. Among any one type of fruit there are dominants and recessives. In apples most trees that are considered "hybrids" are all grafted from 2 apple varieties. Red Delicious is a grafted tree, but is also a dominant, so would be a good choice, since we are a lot heavier apple country, than peach or orange up here, I'm not too sure about others. I'm sure it's on the web. Jimmie was a wildcat though, and he would go after crazy stuff like a Pecherrange, he had a lot of them. Peaches, with Cherry, and Orange, it was like his biggest wish, and none of the individuals  fruited, worth snot up here due to both early frosts, and late thaws. Strange thing was his propagators were strong, so he could grow the trees, they just never grew much fruit, and when he did it was often not what you thought it might be. He made a lot of wine, when he did make fruit. NOT talking about any fermentation process, but fortified wine, of not so great fruit juices, mixed with Brandy or some other strong Liquor. Strong Men might be able to drink it, not I. It would easily clear your sinuses though.
