BTW, most people seem down on the TC coils, but I like 'em so far - except for the fact that my first one gurgles if left upright overnight. It seems that liquid seeps into the airflow control section. Hopefully it's just this coil.
The airflow is a bit better than the 1.5s - makes me want to try the 1.2s. I can take 6-7 second draws - slow lung hits - with great flavor, decent vapor and zero harsh hits. As far as I'm concerned, this thing has got my rebuilt coils beat.
Still on my first coil which I think I installed around the 9/25. I've been using it maybe 70-80% of the time on a daily basis with one of my current ADVs (Lemon Cream from Ahlusion) and it's still going strong. I got 2 TC coils with my GS-Tank (I'm using it in a MS though) and also bought a 5-pack and so far I'm stoked! Been running it on an iStick 40w TC at 430-460F.
I may have to try rebuilding these vertical coils. Will need to search for the pictorial earlier in this thread...
BTW, is it just my imagination or does the airflow on the GS-Tank seem a little more restricted than on the Ms?
