Tstat.....I use my WDZ that way.....works great. If you look at the vid I posted a few pages back you will see it in action. I get about 3-4 hits off of one stem.....amazing. imo no need for tubing, it can be added if you so choose but why? Your going thru that beautiful glass so why not try to keep anything that is not glass to an absolute minimum.....I cut one of my vapor tubes down to about an inch of poly, keeps it much more low profile......I stick that directly into an 18/14 reducer as my piece has an 18 joint.....
