Some good observations there P. You get gunk as you know from experience with a loose electrical connection. Nothing will sour your vape faster. So when a wind does that you know that it's come from over-heating. The venting of radiant energy to the liquid at the winds surface, evaporating some, diffusing it all. Not exactly where we want it to go.
It's best when we can build to match the wick to the wire and flow (both air and liquid).
Yes, these new coils are about some of the best factory coils I've seen. They're designed to target sub-Ω and produce a lot of vapor. And with vapor production comes a lot of flavor. But there is a lot of radiant diffusion of that vapor which makes the resulting texture feel dry and taste somewhat muted
and warm, really warm. The downside is, the more you vaporize the more you gunk. Can't avoid that.
I prefer to target more dense vaporization at lower temperatures and to combine the effects of draw style, airflow and drip tip selection as the means to diffuse the resulting vapor. You can generate dense full clouds, create expansion and most of all max out the best taste results
for you with these techniques. But the main job of the wind, the important part, is converting as much juice flow for the energy punch.
Short of that it's a great effect. But back at the barn we gotta enjoy the vape.
I'm with ya on the stock 1.2Ω at higher wattage, as much as I like the low side. Better density there.
Good luck P.
p.s. brook on the ProtankMicro thread did a straightforward tensioned 29AWG build for the RBA which seemed to work quite well for the center performance range of the Mini (15-20W). Haven't tried it yet but maybe you could and give us a confirmation.
