Here is the first video, skip to around 1:47 for the T-Vape
There is a second video, but it's still uploading so here are some pics of the abv.
And the end result ABV from the second video

grokit My technique has improved and the herb I have now is not as moist so the hits on the first exhale tend to have vapor, I also thought it would be somewhat convenient for you to see a video of the UD vapor versus the T-Vape vapor.
The underdog has an easy draw and will fog up the whole room with one good hit, and several coughs. But the T-Vape is restricted and with a good hit the vapor would dissipate quicker than the UD.
EDIT:
