I'm going to try OF's suggestions.
Having visible vapor is not necessary for getting high. For me having it is necessary though. Perhaps it is psychological but it is part of the experience for me. I think because I smoked it for so long I like having visible vapor as part of the fun. Flower is plentiful and cheap so I don't mind that it is wasteful.
I started in the vaping world several years ago with the Firefly 2 because some guy on the internet, vapecritic, said it was one of the best. I used it maybe 10 times before it became a paper weight and I gave up on vaping. Why? Taste but not much vapor. It wasn't completing the experience for me so that I could stop smoking. Feb 2018 I saw a video by some other guy on the internet, Troy, with the Mighty. I bought it. I have never combusted since.
Fifteen vaporizers later:
One of our trusted vendors told me the Air 2 tastes better than the Fury 2. I already had a Fury 2 coming so I thought it would be fun to compare. I saw a video with Sneaky Pete where he was throwing out nice clouds at roughly 370 F.
At about 10:44
"When I go to 188 which is about 370f you are getting these huge hits with ease just back to back to back"
I didn't get 15% of what he showed when I was at 415F.
I've got some material out getting it as dry as can be (easy to do when you live in a desert). I'm going to put in a fresh battery, let it heat up for two minutes before I start and do the 1 or two hits per minute that OF recommended.
There are times I just have the wrong technique, this could be one of those.
