I just stumbled upon this post today and thought I should mention that I grafted Bu Lu Shu this year with wood from @scottfsmith I think he originally got it from you in 2015, as he sent me what he had leftover that time, but I don’t think it took for me.
Then, this past spring he sent me more and the new graft produced a single fruit. I don’t think it is a rootstock, as it was 29 brix and pretty large. Or if it is a rootstock, what a good one
