I'm wondering if anyone has tried the .4 C3 coils yet. I got some and I don't see much difference between any of the three coils. the vape itself has never felt right to me with this tank. If I close it off just a quarter it feels to tight but wide open the flavor seems weak. overall flavor has been jus OK for me. With the Arco the vape feels better but the flavor seems weak no matter the airflow. It seems like the t6 coils just don't wick well maybe. I get a bit of snap and crackle when I first hit it and again if I leave it a bit but after that it just seems to weaken in flavor and vapor. Just wondering if any of you guys have run into this. I just got a fireluke mesh and it blows these two away for me. Better flavor and the vape comes much more freely. I have been using "The one" in all three tanks. Its a coil killer I know but its strong and I taste it well so it seemed like it would be good for testing.
