Been on dry the past few weeks, and found that some of my smaller glass pieces work upside down with various vapes. Such as small beaker upside down on Angus POTV One, V3pro, etc. with WPA.
Also, with dry glass you don't have to be concerned about waterpiece above the vape, as there won't be back flow.
Having said that, I've just added water to two pieces I've been using dry. I like variety, and if I've been using a piece dry I'll often add water the last day of use. The piece is going to be given a thorough cleaning before being put away the next day, so water doesn't add much to the overall mess at that point.
I feel fortunate to like wet, dry, warm, cool. Don't care for ice in bongs, and am good with water, though I have tried coffee, soda, tea, carbonated water, and a few juices when I was stoned and thought it a good idea. Now I'm just water, or no water. Not enough pay off to bother with other liquids.
This is just my preference.
