I know what you are talking about although it is hard to quantify!
For me it is the lack of draw resistance that allows me to take super big and deep inhales with ease.
The vapor is also different depending on the vape used with it.
For example:
My SV4 will milk it up easily but the exhale is thinner.
My SH milks it just as easily but the exhales are thicker.
With the Glass Symphony they are both pretty similar which is very odd.
This leads me to believe that you require a very specific vaporizer and water tool to combat your allergies.
I am also convinced that the manner in which the hot air is introduced to the herb is critical for you, with regards to material type, consistency of heated air and distance from herb.
I am envisioning a simple type of heated tube with a lot of mass for evenly heated, consistent air.
A glass tube with a built in screen to hold glass beads, could be Ti as well not sure about the beads though... Enail coil with controller should do the trick!
Thanks for the food for thought and for thinking of ways to help. I have found that with various vapes, I suffer a lot more lung aggravation when the load is put closer to the heater.
Very true with the Herbo XL with a raised screen. The abv would come out light tan and fully even, but I would be too iritated by it and not even bother with another load the same and go back to stock.
There is also a certain wooden vape we both know of that has the heater right up against the herb. Although Im totally foggy on its design, and never really considered/inspected it or looked for more info, so the actual heat source may be further away than the part which contacts the load. Im sure you will know these details though.
But this particular vape is also a little too aggravating to my lungs, in a similar way to how other vapes affect me when the load and heater are moved nearer.
The Elev8r- the load is a fair ways off the heat source. When I first tried the smaller bowl, which raises the screen quite a bit closer to the load and also funnels the heat into a narrower channel, I experienced this type of increased lung and throat irritation.
Which has led me to suspect that part of the magic of the elevator is the actual bowl shape and design itself and the distance between load and heater.
No doubt there is more complex stuff going on than we have even got around to considering fully yet. Like the whole venturi effect and the concept of general airflow variation, which we know can drastically alter the extraction and nature of the vapor produced between different devices.
I have since had better results using the smaller bowl with the Elev8r but it is less forgiving and requires more careful torching, in particular to get that pure flavour which in my testing so far has not matched the flavour I get using the stock bowl however I torch, high or low.
So I definitely feel that the bowl shape, design and load distance are fundamental Factors in making the Elev8rr such a pure tasting and smooth heavy hitter which I tolerate better than any of the other equivalently powerful extractors I have tried.
Just a few small tweaks can drastically alter a vaporizers performance to a surprising degree.
With the Roor exhale though, I see such a striking similarity to your own videos with the way the vapor blows in plumes and disperses. Just got me thinking.
Cheers bro hope you are set for a nice evening. No vapor for me today yet, 8 pm here. I have wanted to gather some incentive for some time to leave vaping until later on but motivation has been absent. Your words of wisdom on the whole tolerance thing though has helped me make some steps here. For sure on thoss days I get a lot higher on less weed.
