Atomic's Seminars are now by video, maybe with a mandatory Zoom session afterward for new shops/techs. I'd wait a month so they can have included the added TFX portion. It's already been filmed and is being edited now.
As pointed out before, there's no good reason to use Z3 over Z2 for performance (they're identical, but for trim kit and a Comfort Swivel with a PVD coating). Your cost would be less, but if you're promoting this as your entry-level set, you might want to spend the extra $$ after all, to use the Z3's as billboards during training.
For training, I'd definitely seal them. If your divers learn that way, they'll be more likely to buy them sealed. More important, there is NO first stage maintenance. No worries about the tank falling over on the shore and jamming sand in the ambient holes. No need to rinse the first stage at all!
Just splash them off, and hang the sets on the edge of your rinse barrel with only the seconds submerged. Easy-peasy, and the slightly open second stage valve won't possibly get water up the hose to the first stage. Hang them up to dry the same way and you're done.
