I've been using my LB with my micro bubbler for ~ over a year now, it's the only way I use it now, with the LB, or the FV,
I use one of Ed's wooden stems that fits snugly into the LB, and added some heat shrink tubing on the other end, to make it fit nicely into the bubbler. You could use the glass stems afaik, but the wooden stem seems to mate with the LB so well, and peeps that see it assume it came with the LB since it looks so stock. I found it takes out the harshness of the taste so well by cooling it, and by scrubbing out most of the smallest particulates that get through.
I got the micro bubbler ages ago from deal extreme, they were so cheap, I got about 10, and have given a few out to my friends who have an LB. They all use it, and enjoy it.
Quetzalcoatl: FWIW, the flavonoids do not contribute to the taste of our beloved herb, its mostly all the terpenes and terpenoids. The flavonoids are just one of many types of anti-oxidants that are present in virtually all plants.
