I`m indeed looking for a small volume piece, my first bong was way too big , i was out of breath before the first vapor arrived at the mouthpiece
The d020-d is just right for me, but now i`m looking for a little more diffusion and action. I thought for a recycler maybe a more constant airflow is needed to make it work. With the d020 i wait till the FB is on temperature then i`m taking little sips, and when i see that enough vapor is produced i take a long draw. The bubbler then looks like it`s filled with milk; disconnect the tube and boom
You mean this one?

Looks like a very nice piece of glass. Too bad i will break something like that in a few weeks
But maybe i should look for something similar; small in volume but good diffusion.
