(Original poster thinks of himself as a persistent billiard ball of identity, when neural processing stops, the billiard ball winks out of existence.

Uhm, no. I would subscribe to more of an information view of identity. In other words, if my information state encoded in my brain could be uploaded to a computer and executed in a mind simulator it would have my identity as much as the meat guy writing this right now.

Actually I have no idea what identity is or how many of me there are; I'm the guy who Can't Get Over Dust Theory.

I don't have doubts about cryonics at that level. If the technology works, the technology works and I would wake up as me as I ever was. That isn't where I'm "going wrong".

I do think that identity is lost when information is irretrievably lost. And I think that has likely happened or will happen to everyone being suspended right now.
