I vape on mechs at a little higher resistance than you guys, but I tend to favour restricted direct lung single coil RDA's with small chambers.
I'm on Ni80, either 24 gauge flatwire 6 or 7 wraps (0.44 - 0.5 ohms), or fused clapton 2*28/38 5 wraps (around 0.45 ohms).
And I get a 6-7ml squonk bottle full, per 18650, so I only need to swap out my cell at bottle refill time.
