I use the X2 mini tank on Halo Triton, I prefer the lighter throat hit and zero burnt flavor it gives over the top coil. Some complain about the airy hit of the X2 tanks, and they are, but after I got used to it I prefer it. They do leak a bit but not badly. I rotate 3 tanks through cleaning, drying and using cycle they last me about 2 weeks before they just don't produce much. Hope that helps. I have to be honest, I wanted to like the Triton and really did the first two weeks. I bought a 900 and 1300, they really fell off performance wise after two weeks. I will likely go back to the X2.
