1.3 to 1.4 ohms is my usual target... Kanthal grades and number of wraps depends on wick size though...
Same here. Though I do like the 0.9ohm I have in the dripper right now. It's insane.
For most though, yes, I like 1.4ohm if I can get it with 4 wraps. Any fewer wraps I feel doesn't have enough heating area to make good clouds.
I've also gone off the solid wicks a bit. I now always leave at least enough of a tube to get a needle or paper clip down. The #200 mesh is really floppy and you have a hell of job keeping it straight when wrapping otherwise.
My 2.5mm 7/7 wire rope arrived yesterday and I did have a quick play but didn't have enough time to really sort it - just went with a standard mesh wick for the day.
One good thing, the rope is almost impossible to damage in any significant way, so my fumble-fingered attempts to keep small bit of mesh wrapped while also wrapping wire had no effect on it. A mesh wick would have been all frayed and torn by now.
I'll have another go at it tomorrow. Sad to say the 2.5mm is too big to fit my new Cobra. but the Mesh Company is going all out on vaping supplies now. Mesh, Wire, Silica and rope all in one place. I'll grab some 2mm 7/19 from them.
