Have you grafted before? I may try a couple dozen pears, apples, and plums next year from Cummins. Maybe some nectarines too although my zone is a little tough for them.

I'd like to try some apples on G969. I prefer free standing grafted trees that end up a little larger. I'll probably use OHxF87 for the pears.
