I tried my mech with a .10 ohm build and compared it to the drag 2 set on 115 watts with the same build and tried a double stack witha .3 ohm build. All gave about the same amount of vapor. I think at a certain point u cant get but so much vapor. U cant drip but so much and cant burn but so much. Even with more surface area ur drip is the same. I think Im about maxed out unless I do something crazily stupid.
