Folks,
After several months of Chinese glass acquisition, and all the various glass slides and bangers I've received with the various pieces, I have come to this conclusion:
There are many, many, many different styles and sizes of glass bowls that are already on the market, all of which will give you excellent results when used with the FlowerPot and some degummed hemp fiber (pressed into a thin "mat" as a screen) to keep the vapor path all-glass and herb. It is easy to find glass slides that will fit at your local head shop... just take your FlowerPot nut (the part that engages the bowl) into the shop with you and see what fits. It doesn't need to be a perfect fit... even smaller diameter bowls can be used if you "seat" the flowerpot to the bowl lip properly... sometimes with a bit of fiddling, sometimes not so much. I've found that "Star" screens give the least amount of draw resistance over time as reclaim builds up in the bowl holes... but there are also many single-hole bowls that have a large enough hole to work well for several bowls before requiring cleaning.
People... there is no need for special custom bowls that will cost you 3x to 5x what they should... just do a bit of shopping and you too will strike gold!
This is my testimony, hard earned and treasured: Once you try the FlowerPot with an all-glass vapor pathway, you will NEVER go back to Ti bowls! I have literally not touched a NewVape bowl in over a month now... and have no intention of ever re-acquainting myself with one. Glass bowl flavor is just that amazing!
