I've had my DBV for about 10 months now. I have mostly used it with a 14/14 m/m gg adapter as the wand, and that worked exceptionally well at conserving bud. I went from 3.5g/day smoking to 3.5g/wk using the DBV with the smaller bowl.
About a month ago I got a bubbler (DHgate D020 being discussed in "Cheap Hi Quality Bubbler???") which includes a 18/18 m/m gg adapter for the glass nail. Just the day before yesterday I thought to myself, "Why not use the 18mm adapter as the bowl and attach it directly to the DBV making 100% glass vapor path (besides screen).
This freaking works great. I get massive, great tasting hits without having to deal with a whip. Yeah, I could get an LSV, and I've actually been considering either an LSV or a Sub, but this setup works so well for me that the LSV is off the table. I load the adapter and set it in the bubbler. With the bubbler in my right hand I pick the DBV up in my left and attach to the adapter and hit away. Much better flavor than when using the whip and the hits are thicker also. It's also easier to clean because it's so small, and not attached to a whip.
I had been using my Solo w/the same bubbler for about a month and enjoyed the great taste and low maintenance of the unit to the point where I wasn't using the DBV much. Now that I'm using my current setup with the DBV, I will only use my Solo when I go to friends.
Da Buddha rules, at least until I get my Sub.
