Thank you for the detailed post! I'm getting by with the Aerotank at a whopping 4.3 volts. I ran my Subtank at 20-30 watts and anywhere between .5-2.0 ohms depending on the build with the RBA. I guess I'm a mid power vaper. I also use my a Mutation V3 on a mech to satisfy weird cravings.The GS clearos all have about the same air flow. I'll start with the two I use most: the M and MS are pretty restrictive compared to the Subtank. If you own a Subtank Nano or the first gen Subtank Mini, the GS Air MS and M with the AFC ring wide open provides airflow comparable to the Nano/Mini set somewhere between the smallest and middle settings. It'll certainly allow direct to lung hits, but nothing in the way of how the Subtank does. The original GS Air is about the same (MAYBE a bit more restrictive), but is adjusted with a tiny screw instead of a ring. It whistles a bit more, too. The GS tank provides the same airflow, maybe a TEENY bit more, but is the quietest of the four tanks.
Compared to the Aerotank, the GS tanks provide a decent bit more air flow. It's certainly noticeable, but nothing massive or terribly noteworthy.
With the TC coils, it all depends on how you vape now. I tend to vape at higher wattage settings (20ish watts with the GS Air coils and 40+ with my Subtanks, both with kanthal coils) and settle in around the mid 400 degree to 500 degree mark with the GS temp control coils. With the Subtank, I go all out and hit the mid 500 degree mark to as high as 600 if I'm feeling rowdy. But keep in mind that I like a good and warm, dense, wet vapor. You may not. If you like a cooler vape or typically vape at low power levels, you'll likely need to adjust accordingly. That's all going to come down to trial and error and personal preference for you. The TC40W certainly makes it easier for a beginning temp control vaper, though, as all you need to do is adjust the temp cutoff... the mod automatically maxes to 40 watts and can't be adjusted. Nice and simple.
Incidentally, if you dig the iStick Mini, consider the updated Mini. Eleaf/MyVapors/iSmoka/whatever-powers-that-be released a 20 watt version of the device. It's all but identical but now supports up to 5.5 volts in voltage mode with a 20 watt cutoff. It also offers a real, no-kidding wattage regulated mode that supports 8.0 to 20.0 watts in 0.5 watt increments. All for the same price. Great battery for the teeny GS Air MS, especially with the newer 1.2 ohm coils... just sayin'; not trying to promote shinyitis or anything.
I'd love to add the new 20 watt , but I just dropped about 50$ on the TC setup with mod, tank, and coils. Is probably better not ask my accountant for anymore stuff for a while.
