The Vapolution with the AIW bowl is also all glass, but I find it harsh
That's because you let the temp get too high, which is easy with the Vapo. I've got years of experience with this model, and if you're careful the hits are as smooth and mild as the fixed temp CRZ (same top loading design, just easier to overheat with the herb deep in the Vapo bowl). There's nothing whatsoever to make the Vapo hits harsh except the temp, which can be controlled.

Balloons are for people who like stale smoke.
A lot of people like the bag fill method just for convenience, and I think you mean vapor, not smoke. OTOH I don't see why anyone looking for all glass vapor path would consider drawing vapor from a plastic bag.
If your taste is refined enough to appreciate and detect ALL GLASS, the options are limited. If taste isn't driving the decision, IMO it's silly to avoid stainless steel. And in a double blind taste test, I'd bet that most people who claim they can taste a ss bowl, really can't.
