(Copying some from this reddit comment of mine, about China glass I've ordered to test with my VapCaps. They might be sold out but similar items are generally available.)
Small with surprisingy little/no splashback !! But the mouthpiece stem is quite thin, so be gentle and careful

I LOVE the next 2. They've become part of my daily pieces. Incredible value IMO
https://m.dhgate.com/product/bongs-glass-bong-glass-wter-pipes-bubbler/395681180.html (not sure if lead paint is on the mouthpiece... someone can give me a heads up!) They both use surprisingly little water very effectively. (Pretty important for me)
Simple 10 inch straight tube

Another one which has entered my daily rotation is an 18mm Mobius matrix sidecar style clone from amazon.ca (was incorrectly labeled 14mm) but the price (23 CAD) was so good, and it still works great with a 14-18mm adapter or even with the included glass bowl upon which the VapCap mouthpiece can he held, that I'm overall extremely happy with this and most of my other purchases.
Overall, quality China glass is quite worthwhile for now; have no fear about going for the bigger units if you want extra smoothness. I do also love the Orbiter, but it's pretty pricey relatively, and replacement Orbs are 30 USD. (Magic-Flight's Bottle Rocket could be hooked up to a VapCap a couple of ways, if you fancy it.) My preference is for 14mm female joints or bowl areas which can accommodate the 10mm mouthpiece.
Has anyone else used degummed hemp fiber as padding at the bottom of the Dynastash and VapCap tubes? It's actually my only use for it, but what a practical one it is.
Also, am I the only one who gets super hyped for George's longer streams ? I love listening to him speak, I love basically everything about him, in a very straight way. A beautiful man, who has brought together such a great community over the love of his vision and ingenuity. Cheers all Dynafriends!
