Jordon, I've heard from others in Florida that the white sapote in Florida are not nearly as good as the ones from California. I'm not sure why. I've seen photos of some really awful-looking white sapote in Florida. I've also heard some people that like mamey sapote and others that don't. I guess it's good that we don't all like exactly the same things! I may still try mamey sapote some day, though. Sapodilla is one I also want to try some day but I'm not sure it will make it here.
Here is a photo of a grower in Brazil:

Yours sound great! How many times a year do you get a crop?
