In one of his video e-cig reviews, igetcha69 made a great observation that people choose between different atty and voltages in a subconscious attempt to find a mod that most closely matches their style of analog smoking. I personally think it is one of the most astute and brilliant single observations that I have read about vaping.
There's only one mod that I know of that attempts to rectify this problem...the 2nd and subsequent versions of the GGTS with its adjustable draw feature. I haven't tried this version, but postulated that it would add yet another level of complexity to an already very advanced mod.
