Fairchild off of my tree this year was awesome. Fairchild seems to be a moderate grower in my yard, at about the same pace as Carrie. Im not sure if this is the universal experience or just my yard. And its a very atrractive tree. No disease issues at all.
The mangos arent brightly colored and this is good ; less attractive to 2 legged critters....just my limited experience. NDM is a delicious and adding an asian mango , if you dont have one, may be the thing to do. Im not sure why NDM isnt a firat choice other than splitting issues, which may not be a problem in your area (my neighbors tree hasnt had a problem )
