I bought the Evic-VT. Won't use nickel, as I have reason to believe I'm probably allergic to it. Titanium vaping was completely underwhelming; no TH, very little flavor at all, and with my super-gunk juice, one day's vaping is all she wrote before the coil has to be replaced, which is completely unsat with wire that costs more than twice what kanthal does. Sold the Evic-VT within 2 wks of getting it. No plans to buy any further TC mods, unless/until the SX Mini M class becomes affordable -- I just like the way that one looks, but will probably run it in wattage mode, given my dislike of titanium.
1.7Ω kanthal coils at 9w are all the temp control I need, and it also gives me excellent flavor. Unlike titanium. My titanium Achilles is all the titanium I need.
