Interstem questions

Alright folks - I am going there. I know this thread has focused on apples and pears, but what about other “non-traditional” fruit? I am particularly interested in if anyone has tried an interstem for pawpaws?

Obviously disease resistance/dwarfing characteristics aren’t as important as with apples and pears. I am particularly interested in passing traits such as high vigor onto less vigorous cultivars. I was thinking mainly about using ‘Mango’ to possibly reduce the years to bearing fruit for other cultivars as KSU Chapell is patented and I’m not sure on vigor compared to ‘Mango’ for others like Kentucky Champion and Regulus (two others that might fit the bill). So has anyone tried it, and any good results? @Barkslip @TrilobaTracker @Blake @RNeal @mamuang @PharmerDrewee or anyone else?

Are there any other specific traits that I’m not considering that I should be? Am I over-thinking this?
