Ok, now that I had more than a few ripe fruits on my Supersweet and Younghan's Gold grafts, I can give you some feedback on taste. Younghan's Gold is the one you want, it tastes good, fruit is medium size, much better than Supersweet. So far, this year is the first time I had fruits from Supersweet and there were many on my grafts but I did not like the taste of this fruit.
I would say of the fruits I tasted so far, these are the ones I like and will keep on my trees:
1. McDill
2. Cuccio
3. Younghan's Gold
4. Yellow Sapote
I have one Walton fruit now, it should be ready to eat in another month so I should be able to comment on my first fruit.
