Oh and Mike I would not recommend the Lemo at all. I have had nothing but problems with it leaking out the fill hole. Tied the gummy thing no go tried the screw same problem and it is harder then hell to get in. I'm leaning more towards the Kanger. I can imagine that the KFL+ wouldn't work well. It seems you need good air flow to make these work well. My Lemo is by far the best build but the tank has some major issues in my opinion.
