I think with convection and short vapor paths, the distinction between "great smooth vapor" and "I just kissed a hair drier" is very thin...
From my experience, as soon as the air / vapor ratio is not satisfying, one starts to perceive more harshness and more of the "just sucking hot air" effect. This has two implications:
- You really need to find a vape that copes with your drawing speed and intensity, as it's easier than trying to adjust the way you draw. If you want massive air flow and very little restriction, you'll need a lot of Watts. Otherwise having the vape create the right amount of draw restriction also works quite well (and this is where the difference between 2 and 4 holes Splinters is key, carb'ing the air intakes is another solution)
- It took me some time to understand the second implication, but I think TC mode can be perceived as being harsher compared to Power mode, because progressively, the air / vapor ratio is getting worse and worse, the more you deplete the current "temperature level". And you need to remember to increase the temperature regularly to counter that. The problem being that in order to realize that it's time to bump up, you need to get a couple crappy wispy hits first, and thus more harshness!
We don't feel this effect much in Power mode because consciously or not we adjust our draw and trigger times in a much more natural and organic way. This is how we can achieve the same temperature ramping up but in a continuous fashion and not in discrete steps like we do with TC (unless you bump say one half degree up after every hit...) That plus the natural heat soaking of the vape + stem/bowl system over the session time, gives a very fluid experience.
Starting TC mode at max temperature (in order to not bother with the temp stepping) doesn't achieve the same result as Power mode either. You get the hottest possible air right from the start and all the way through the session, whereas in Power mode you only reach this extreme temperature for the very few last hits before the bowl is cashed.
So you all know how much of a TC advocate I could be in the past, I imagine what I'm saying contrasts with my usual enthusiasm... But somehow I wish we could combine the best of the two. I would like something natural and organic like Power mode, but coupled with the "idiot-proof-ness" of TC mode that gives me this much needed safety belt in the form of the insurance I'll never ever combust (and if setup right, that's I'll never ever char my load)
Because as much as I love Power mode, I really *hate* when with just a single mishap, say because you were distracted and fumble the trigger timing, you can ruin a perfectly fresh bowl and get a damn center black spot that completely spoils the taste for the remainder of the session (you can stir all you want, when it has roasted too much, it acquires that crappy taste, the only solution is to sort the black bits out of the ABV and discard them and it's a fucking pain and not fun at all)
What I would like would be having a mode that behaves exactly like Power mode, until you push it too much and then it caps the temperature and falls back to TC mode. The trick being that the cutoff point between the two modes should be automatically variable (otherwise if that's just the temperature before combustion happens, it wouldn't prevent hot-spotting... afterall when we hostpot we don't combust either, it happens before that)
So it's a bit ill-formed and maybe the best solution would be to just acquire the habit of bumping the temperature after every hit? But unless you manage to setup TC mode very well, you end up in practice with not that many usable temperature steps (and worse, some mods only allow +/-5 degrees change with each click) Other vape makers already tried to introduce automatic temperature stepping in the past (even as far back as the Ascent but perhaps even earlier?) and I always disliked that because it tried to impose a fixed walking pace on you and I perceived that as a loss of freedom (i.e. me being forced to adapt to the machine and not the inverse)
You see it's not a trivial problem... I still don't have found any practical nor elegant solution.
PS: the problem with previous auto-stepping modes was that it was often timer-based and applied to conduction vapes. Most vapes lack the ability to detect hits, but a few of them do (like Firewood, but it can be apparently tricky as some hits if too weak can go undetected) Here we have the advantage that we can detect easily each hit when they are on-demand: just watch the trigger button state. So maybe we could just add a mode in our custom firmware to auto-bump the temperature after every trigger press with a small increment (user selected to cope with those who cash their bowl in 3 hits vs those like me who do the same in 30 hits, I would probably need for instance much less than 1 degree increment after each hit... or perhaps not, going from 190°C to 220°C is only 30°C afterall)
PS2: even better, I would like this increment to be non-linear. When I use conduction vapes, I spend much more time in the first few temperature levels than I do in the upper ones. When you do a proper temperature ramp, you spend very little time at the max level because there's practically very little left there. So the increment should have an exponential curve or similar, staying with a gentle slope for a long while then ramping up faster at the end of the session.
PS3: I've been running ArticFox for a long time now, maybe someone will just tell me @funkyjunky already implemented that feature in his firmware? The problem is, tubo_myevic is really lagging (stagnating in fact, still at the my_evic level) when it comes to device compatibility. It's normal after-all, he customized it to support his vapes so his firmware works for the mods that are inside his products. But AF has much more compatible devices... unfortunately it's closed source so we can't easily back-port that. And AF devs are not very open to feature requests and even less if they are not for e-liquids...
