Very nice vid, thanks for posting!!
also about my favorite china piece... it's really hard to pick, but I would say at this point the 187 seems to be at the top of my go to, for size and function. I would suggest the D022 as a next pick, but it seems out of stock. Between all the smaller pieces, I think the 14mm kathy recycler is my current favorite, but I would say the D020-D would be next in line. I guess I favor that style bubbler for low drag and lots of stacking.
The super mini-rigs are cute and do function, but are a bit of a novelty for me, and I think I wanted them more for having a milestone in the glass movement, part of the glass evolution seeing them shrink down so tiny. Also I hope one of the last side effects of the death rattle of prohibition, we shouldn't have to be so sneaky... but I digress... back to glass goodness.
