I'm about 4 fruits in this season and they're pretty much the same as last year. Bit of fiber around the seed. The rest of the flesh isn't completely smooth, its kind of grainy. Nice flavor. Coconut or Pina Colada, but not strong on the pineapple.
The rootstock appears to be called 'Camarillo' and I think its the air-layering stock he discovered while selecting his mangos. A failed graft. Parallels with the Hass avocado.
I do have seeds now and i guess I'll plant them.
And i have started to top work. Sweet Tart so far.
