Damn, I haven't wrapped a coil with anything thinner than 32g in quite some time, but I think I'll give it another go when I get back from my trip. For some reason, the thinner wires seem to actually hold up better at high wattages than thick wires, not to mention they seem to gunk up a little slower, and when they do gunk up, it's a bit more manageable to adjust the coils with 34 and 36.
As far as the OPs post, I've found that more spread out coils produce a cooler vape, where as a tighter coil (more akin to that of iAtty) definitely has more kick to it. With Ody, I find myself wrapping wider coils, which I guess is b/c I like to take advantage of the full 6mm of space, but my Pene coils usually turn out more like my iAtty coils, much tighter and closer together. With ody, I've been using doubled up 3mm wick and with Pene I use a single strand of 3mm wick (mostly b/c I usually don't have the vertical clearance to squeeze in the 2nd piece of wick). As far as wire, my last 2 coils have been with 28g kanthal(both around 0.9-1.1Ω), but with Ody, I've been using 30g kanthal for probably the last 3 months and just haven't gotten around to trying 28g in em. As much as I like how it vapes (especially in genesis atomizers), I'd steer clear of using the 28g in Ody and Penelope. The stuff is just too damn thick to do a clean job of twisting it together with the NR wire.
I originally started with a 32 awg just because that's what many people recommended but I ended up using 36 awg after Imeo suggested it. I have found that, for me, the thinner the better. Thinner wire heats up faster and I'm able to take shorter drags while still getting a ton of vapor and better TH. I used to think that more wraps would give better performance but I found out that the number of wraps is indeed not as relevant as the gauge of the wire. If looking at a 1.5 ohm coil, I will take 2-3 wraps with 36g over 4-5 wraps with 32g every time. Just my preference based on what I've experienced...
