How long is the Sub Ohm Innovations Shorty & Legendary? I checked the SOI website and all I see is diameter. I bought a SubZero off a friend and he said it was the "regular competition Sub Zero, not shorty" Was there a earlier version out before the Legendary? It doesn't have the lock ring of the Legendary and the button looks like the one on the Shorty. It's about 3.5" long (approx. 88mm give or take). I'm guessing it's the shorty and that he was just mistaken when he said it wasn't.
