Whilst I am happy with my current build, (SS316L, 26g, 3mm id, 9 wraps, 0.5mm spacing, dual coil @ 0.3ohm combined in Big Baby RBA with Native Wicks cotton minimal wicks @ 47w = flavour NIRVANA, no leaks, 1 week between wick changes and 8 months now on same coil!). I am looking to try some 28g or 30g coils for a faster ramp up but more importantly for a quicker cool-down as I can still hear hot juice on the coil after I've stopped sucking, even when I've let go the power before I've stopped sucking. I want to keep using between 8 and 10 wraps, maybe going from 3mm to 3.5mm for my id, but I see when using Steam-Engine that my expected ohms will be 1.6 to 1.8 per coil, giving me 0.8 to 0.9 ohms per dual coil set up. Does anyone have experience of just barely sub-ohming like this? If so - what was it like?
