One that will fit the dual coil SmokTechs similar to the way a Boge looks on it... Not necessarily for aesthetic reasons but more for support of the cartomizer. I like being able to just shove the whole thing in my jacket pocket without having to worry about breaking anything.
To be specific, it's the top hole size that concerns me, not the overall length. Just need enough to give some support to the longer, wider cartos.
