Thanks for this thread, it reminded me that I'd yet to try either my Taifun GT2 or SquapeR (clones).
Squape will have to wait until tomorrow but I got the GT2 up. Unfortunately I don't have the Hotcig version Steve mentioned, but mine has turned out to be not bad. It's the same spec as Hotcig I think:
GT-T V2 RTA Rebuildable Tank Atomizer (5.0mL) stainless steel + matte glass / 23mm diameter (SKU 2075000)
The only problem I had was that the screws are awful - really small heads. I got one wire tightened down quickly, but the other took me ages and ages and was really annoying - eventually I got it in place using my Helping Hands to hold the mod while I pulled the wire taut with pliers and screwed down hard at the same time. Even that took many attempts. I also used
@WeirdWillie 's trick of lubricating the screw/wire with a drop of juice so it's less likely to be pushed out or pulled round by tightening.
Then I found my 3.0mm twisted wire (2x29G) coil was too fat to fit between the posts, so I had to elevate it to mostly above them - further away from the airhole than I'd usually want for flavour.
But wicking (Rayon) was easy, filling was easy and it didn't leak a drop. Airflow seems fine - I don't like huge gales particularly. I have with all holes open and that seems about right for me - I might try one hole less at some point too.
As for TC, it's working well. I am using Resistherm NiFe30, twisted, 2x29G, a mostly-contact coil; a couple of gaps I couldn't quite close because the twisted NiFe is springy as hell. But it holds together well once it's been pulsed a couple of times.
Vaping it on my SXK Flask at 420°F with Nickel Purity set to 40 (+8 compared to Resistherm's 0.0032 TCR) which is quite a bit lower than my calculator told me to use based on the SXK's low resistance of -0.07 on this coil (NP45 was calculated.) So I think there's quite a high static resistance in the atty itself - 0.03 at least - or else I possibly didn't get quite as firm connection as possible under those screw heads.
But it's stable and vaping really well at 30W. A really nice vape and not bad flavour, especially given how much gap I had to leave between coil and airhole. I really should have tried it before!
Tomorrow I will have a go with my Squape clone - the idea of non-conductive deck really appeals to me. Unfortunately I have a clone where the W deck won't fit on properly, I think only S and C work. Presumably I can file down the holes on the W a bit to get it on, though I don't know how fragile this deck material is?
I also have a new Rose v2 clone I've yet to try which looks kind of interesting - and complex! I took it apart to clean it end of last week and all the bits are still sitting around my ultrasonic, I've not yet bothered working out how it all goes back together
