Just bought a K100 for the size (it's smaller than the ProVari in 18350 mode). I normally use carto tanks, and most of what I have can be described as big. I am trying to find something no-so-big to top my K100, in glass, and not a clearo (ProTank, Evod, or Vivi Nova). I think my 19mm IBTanked are too big for what I want. Suggestions, please? Thanks 
ETA: BTW, yes I have already considered an rba for it as I have a couple, but I really do prefer my carto tanks.
