Well, the Squape was my primary atty for 3-4 weeks (which is longer than anything else has ever lasted as a primary for me). It was a terrific atty to learn to build on. But then I got a Russian 91%. I actually wanted a KFL+ but couldn't find one that I could be confident was genuine. Anyway, the Russian is now my primary atty and the Squape has been taking a break on the side-lines because I only have one mod suitable for a "full sized" (22mm diameter) atty, and it ain't the Vaporshark.
Of course the Vaporshark is perfectly capable of driving either a Squape or a KFL/Russian but the resulting overhang on 3 sides bothers me, so my Vaporshark is currently adorned with an Aerotank that has the head rebuilt with a single micro-coil and cotton wicking, which provides a surprisingly good vape.
Some people look at me funny when I tell 'em that I rebuild the heads for that. I suppose they're wondering why somebody who can afford the stuff I vape from would rebuild Kanger heads instead of just buying new ones for the couple of bucks they cost. Well, I don't do it to save money, I do it because I like the results and I have yet to come across a 19mm device that works better. I had high hopes for a Sophia in a 19mm tank, but I'm not getting much joy from the pre-built coils that came with it and the NR-R-NR wires I've ordered aren't here yet.
