I've been making 1ohm coils with round kanthal for yonks now. Although, i don't need to !. A coil lasts for what seems like forever. So "building" is something i rarely do !.
I went through a learning curve and found what works best for the kind of vape i was looking for.
For strictly mouth to lung vaping using low power, at 11.5 watts, i'll only ever use 29g kanthal, 5 wraps, with a 2mm inner diameter. For me, there is absolutely no need to use anything else !. 29g, through trial and error, is the correct thickness i need. I've tried various types and thicknesses. 29g is rigid and perfect for re-wicking whilst not becoming deformed. So much so that a coil lasts a very long time.
Anything thicker needs more power so batteries don't last, the vape's too warm for me !.
Less power with thicker wire means a coil takes too long to heat up (ramp up time).
Anything thinner and the coil will deform when i try to re-wick, so i end up having to build a new coil !.
Vaping doesn't work for me with anything other than 29g kanthal.
With several identical tanks in rotation, all with the same build there's no mess, no fuss !. A wick get switched out every day or two and will only take a few minutes.
My vaping style includes one 2 second primer draw immediately followed by a "second" 2 second draw which provides a throat hit. I've been vaping this same way for about 7 years.
I am currently using a Smoant "Charon" TS 218 box mod. I rotate several Svoemesto "Kayfun V4" RTA's.
All this is combined with 24mg D.I.Y e-liquids made 80ml at a time x ten different flavours. The costs are as minimal as they can be.
I simply cannot be bothered with high powered, dual or multi-coil direct lung vaping !. Too much effort goes into the inhale.
My style of mouth to lung vaping is effortless, and practically maintenance free !.
Vaping doesn't get any easier than this, and is no more complicated than using a pod system.
Alright !, but the difference is negligible, and a lot less expensive !.
