I've never tried any build fancier than simply 2 wires twisted together, which I tried when I was giving titanium TC a go. I don't want a lot of vapor, so anything more would definitely be unpleasant for me. I didn't like either titanium or stainless, or really, TC at all; titanium just doesn't bring the flavor at all, it's muted as hell, or maybe that was because of the TC, I dunno. Stainless is kinda the opposite, TOO MUCH flavor, but not a flavor I wanted -- I tasted the cotton itself, whether I was in TC or wattage mode, with stainless.
I suspect my trial of titanium TC just wasn't a very good trial, with one of those Joyetech VT things, the originals, when they first came out. My later trial of stainless TC with my Coolfire IV TC-18650 was a better trial, but I found it simply too hot to be able to enjoy it -- it starts the coil up at 30w, which is THREE TIMES the wattage I normally use, so that even the lowest temp setting was still too hot for me.
So, I'll stick to my kanthal 29ga, 8 or 9 wraps around 3/32, coming in right around 2 ohms, and running about 9.5-10w. Works great, vapes just the way I like it; ever so slightly warm, but never hot, and never so much vapor that it chokes me. The "cloud" produced seems quite similar to what I exhaled when I smoked, so it's JUST RIGHT.
