Oscar, do you have the fiberless or other select cultivars of soursop? I didn't notice them on your cultivar scion list.
I haven't eaten a lot of soursop but I have noticed huge variation in them here. I have had some that were quite good but not as good as atemoya or cherimoya (although I don't doubt that there are some that are as good or better) and one that was horrible. I guess that is the problem with seed grown fruit, you don't know what to expect quality-wise. People who would probably never buy an "apple" without a varietal name (like a Delicious or Mutsu) will buy tropical fruit with no varietal name. No wonder some tropical fruits have such widely varying reviews.

Jay, you should suspend further judgement till you get a chance to try fiberless soursop. Looks and tastes almost like a different species or sub species, with its bluish cast leaves. To me it was equal to or even better than some cherimoyas. Truly a delightful surprise. I've yet to find one though that is a good bearer. The Whitman fiberless makes very few fruits here.
Even regular olde soursop is quite excellent in juices or ice cream! Just not so great out of hand due mainly to all the fiber--NOT the taste. Some have quite good sweet/sour taste.
