Alex, wow, I didn't know the Pantin fruits get so large. Very nice looking fruit.
If you take cuttings from the tree, I would be interested in buying a few small (1/4"-1/2" diameter) cuttings. I think I have a green sapote which has not had any flowers yet so I want to graft a fruit scionwood eventually on the tree. My tree is about 8 ft tall (skinny, no side branches).
