Wow, finally got the 30awg ka1.
Started with a 2/3 wrap on a thin/fat wick and it damn near made my head explode. I consider myself fairly rough and tumble, but a 0.9ohm coil on that wick (18mg/100%VG@3.2v) lead to an immediate nic headache (fair warning!). I decided to try a 3/4 and crushed the wick (my fault). Long story short(er), new thin/fat wick with 30awg 3/4 wrap measuring in at 1.2ohm is really nice. Tons of vapor, tons of flavor and nicely warm.
Pretty tough stuff... It's definitely thicker wire and a bit more rigid which gave me some issues trying to get the right tension (how I crushed my old wick). Might just be my two left thumbs, but worked great wrapping on my Home Depot pick-tool and then twisting in the wick (with a nail still in it so it didn't collapse).
Strangely, at 0.9ohm my VV Gripper consistently faulted with "Lo" while the ProvariV2 seemed to handle it just fine. Not sure why since the PV2 has a 3.5amp switch and the Gripper is supposed to be 4.0amp and both were set down to 3.0v.
