I bought some Kanthal
I do get popping but its not pronounced except on the first hit. To be honest its really not that much of a bother for me; but everyone is different and I have definitely not had hot juice exploding into my mouth like you described. If this thing leaked I would be severely disappointed since I bought a tank for ease of traveling/driving. No leaks and vapes great.I've rewicked a few times and still get it at varying degrees. Thickness doesn't seem to make much difference. I cut the wick a little shorter than I had been, and it pops less, but is currently leaking through the air flow holes, so I'll have to cut a new one at the previous length.
It may just be me, but I've noticed a decent amount of liquid in my wide bore drip tips, so perhaps it's something to do with my chimney. I'll keep experimenting.
