Yeah , maybe tree immaturity was a factor last year. The fruit were left in the tree as long as possible. I let 3 of them, in the 30lb range mature up. One of them I waited until it completely softened and partially blackened on the tree. Same result - latex free, crisp, and low flavor.
I purchased the tree at the Broward rare fruit council sale a few years back. Graft line was low , and is now difficult to see. I would love to see a fruit from below the graft line, but as of now it's not happening.
