I planted my HM a few months after you. I will have a small to medium crop depending on how they hold this year, first fruiting. I have not tasted them yet. Not a precocious tree from reports i have read. I have not heard any raving reviews on flavor, "better than Glenn" which doesn't say much to me.
I think we are in similar situations with rain and fungus Forget rapoza. Good fruit but poor disease resistance.
Venus, Angie, sweet tart, and maha do good for me. Venus is slow growing but that may be from my laziness. It holds fruit too well and I have to thin it. Best late mango I have tasted but I have not tasted some of the newer ones. Angie and sweet tart grown by me are ugly on the outside but taste great. Maha will look and taste great.
Beverly and glenn do nothing for me. Might as well wait out harvest moon before topworking to those. Had to spit out Duncan at fruit and spice park a few years ago. Multiple fruit tasted equally bad. Tree was in a funk that year.
