That's what is so odd about the mighty+ compared to the solos I've used...I've used them all through a bong (dry) and I still only get this unique burn/tickle from the mighty in a very specific part of the back of my throat. The others don't do this. Really odd. As far as functionality though, for two years it was my main and worked fantastic. No issues. I still use it now and then, but I get that burn and don't end up reaching for the vape in a long while. I assumed all vapes did that until after a couple years I tried something else.
I was curious if this burn/tickle thing occurs with the venty as well. The Venty is a very unique vape and I would love to try it....at some point. But if it does cause that burn or tickle, id rather not. It worries me because after trying 4 other vapes, it is the only one that does it. At least in my case, since it is noticeable, I probably would pass.
Forgive me, I'm not familiar with the term "high calorie vape". I'm assuming you mean you can consume the herb quickly at a higher rate of airflow? So the assumption is that the higher rate of airflow causes the added dryness and therefore tickle? Is that what you are saying?
Honestly I really enjoy these discussions. I will try to break this down, in terms of different types of discomforts that some vapes can bring according to their materials.
There is a fresh tickle that comes from vaping even in the cleanest air and vapor path: this is from the terpenes as they are very strong substances with some irritating properties, some are solvents, etc .... What we would like is a vape that only gives this type of discomfort. This is rare. The only vape where this is the only discomfort felt for me is the Silver Surfer with baller heater.
Let's now go to level 2 of purity, down the list. There is now discomfort of metals used in the vape. For me this is the Tempest. Still the best choice after the surfer. There is a specific discomfort when one moves away from all glass/ceramic heating, but is not deal breaking for me.
Level 3 purity, we get into Venty category, discomfort from mixed materials/discomfort from superheating air.
The term "high calorie" used above, I would maybe boil it down to super heating a small portion of air. For example, comparing the balled silver surfer and the venty, the first has a long column filled with balls offering the air tons of surface area for heat exchange, while the latter needs to heat the air to a similar temperature in only an inch and with little surface area. This means the temperature needs to be much higher, I suspect this is not the best design and would explain the success and quality of vapor that ball vapes offer.
In contrast, the milaana has a similarly "short" heater but no tickle. This leads me to suspect that the main factor for tickle is the materials used. As has been in the mighty, and will continue to be as long as better materials are not used. Don't get me wrong the Venty one of the best vapes if you regularly share it on the go. But I can't see the difficulty of making a cooling unit that is PEEK on the outside and lined on the inside with metal, or see the need to use plastic near such a strong heater...
Another type of discomfort that is not related to material "safety" or quality, is heat. Some vapes allow lots of heat to reach the throat. The milaana, the solo 3, any device with too direct a path. This can be ameliorated through water filtration and different stems, but should not be ignored as for some individuals prone to dryness this can be more significant than even the materials used....
