Ok, here's a bit more.
While I still maintain that the SC tube provided the smoothest hit that I have ever experienced using cold water and ice, I did notice a bit of a lack of potency from when I either dry vape directly from the vape, or vape through very warm water, which is what my preferred method of vaping has been for over a year now, so..............tonight I won't use the cubes and will try the SC with very warm water to see how that works.
The bit of lack of potency I'll assume has to be the added condensation that takes place when vapor hits something very cold along with the added diffusion that I wasn't getting from my mini-beaker.
Will report back again either tonight or tomorrow with the results.
But again, to reiterate, the workmanship is impeccable and the size, for me, is just about perfect and the size and angle of the of the stem holder is also perfect......for me. If one is looking for a smooth hitting indestructible bong that is virtually impossible to knock over due to the VERY heavy base, I recommend this highly.
Oh, one more thing. In the flight manual, Steve suggests priming the base of the vape with very cold water (water that has been put in the freezer for 10 minutes) for a minute, and then dumping that water and refilling which allows the stainless steel to get very cold and maintain a cold temp thru the vaping session. I would imagine that the same principle would hold true with hot water, and that the bong would retain the heat longer, which for me, could be a major advantage.
