Jack, That is the SGW tube due to the ice pinches. I can't wait to get mine, I have yet to try a hydratube.
I was able to have a small sesh with my Cloud just now. First impressions are that it runs a bit colder than my first unit, which I'm stoked about because I enjoy low temp stuff. I only had a few rips at 12'oclock, and the ABV came out about as light as what 9'oclock on my previous unit was. I am really really excited to see how low 7'olcock is on this unit. Ironically I was using about the worst quality dirt-weed I've had in a while and it made great clouds and great taste on the first hit.
Non-cloud owners may get the impression from a few posts in this thread that to achieve optimal hits you need to have the ELB in there while it heats up, as well as wait beyond the first indication of a green light. In my experience, tossing a cold ELB into a Cloud that just turned green will yeild the thickest, tastiest, lowest drag vapor I have experienced.
I finished the bowl off at 3'oclock for a nice medium brown ABV. (horrible bud btw)
My unit also had the "SM55 OK!!" which I thought was a great touch. Thanks again SM.
One thing I have noticed about the Cloud is that a large temperature addjustment can take almost as long as the inital heat up, even a temperature reduction. Not much of a big deal.
Thanks again VXH team, I feel that you've got me covered now.
