When I first got my Kraken, I kept stubbornly trying to get the wrong size SS Rope to fit using dual coils, which didn't work and I gave up on it. Being that it looks so darn pretty (naval brass ...), I picked it back up again several weeks later and gave cotton a try with dual coils. Nope.. dry hits like crazy. Couldn't take it out with me either, so I basically viewed it as an oversized dripper.. kind of awkward with no real use.
Finally, several months later, just recently actually, I finally picked up some mesh and decided to build it the way gennies were intended. Single coil with a ss mesh wick. (albeit, 6strands of 32g twisted, .7ohms. :>)
Vapes wonderfully now. Glad I stuck with it. Gennies are a unique vape, mesh gives more of a crisp taste than a dense taste. Not a dripper, not a kayfun, but definitely worthwhile. Great, warrrm flavor.
