Mr. Clean, thanks for the input. I did research disease issues and that was why I selected those varieties. I'm just going off of what the descriptions on PIN and Top Tropicals have on there site plus what posts I've found on here regarding those varieties. Can you comment on the disease resistance of the ones I've listed? I read that LZ does have a few problems in that catagory.
Pickering - I recommend this. Decent tasting, productive, disease resistant and dwarf.
Florigon - you might look into this variety, but has a reputation for becoming large tree.
NDM - seems good, but lots of fruit split; most of my crop dropped this year.

Mahachanok - my trees haven't fruited yet
Rosigold - susceptible (but blooms early to avoid part of rainy season here)
Graham - seems good, large mangos, but a boring tasting mango. I would have planned something different in hindsight.
Mallika - my tree hasn't fruited yet.
Lemon Zest - about a 25% of my crop split
All of my trees are 1-3 years old, so you may get different results in the long run.
