Try the Desire M tank Mesh 0.15, I like the coil, not so much the M tank though. I'm getting a little better life out of them for some reason. I ran it for 2 weeks in the M tank, then swapped it into my Joyetech Air, been there for a week and still good, really liking the coil mainly for the longevity. Running it at 55W, It is rated at 50-90W.
