6 wraps of 29 ga around a 2mm installed horizontal. It's 1.1 ohms. ... I can't really say why it's "favorite" though. For a single coil on the
device I run singles in, I'm pretty happy anywhere between .9 and 1.1 ohms.... and I've done it with 8 wraps on a 2.5mm with 26 ga, 6 1/2 wraps (installed vertical so the half wrap) on 2mm with 28 ga, 24 ga 8 wraps on 3mm etc etc etc. ... 29 ga was the first wire I bought for a rebuildable, so maybe it's my favorite out of habit.... but then, that PV has substantial v-drop and doesn't have a switch that can take super-low ohms, so maybe it's just the speed the thin wire heats up that makes me like it. I'm not really sure.
Normally, I wick pretty much everything with KGD cotton, but the single coil atty I use the most has been wicked with ReadyXwick for a few months now... I can't say either one of those is "favorite" or not. They're both produce very clean flavor. The cotton is cheap but requires replacement often. The ReadyX is expensive but dry burn it until the
juice in it catches fire and then rinse it under the tap and it's snow white again. It lasts longer than a coil will.
