For Avocado24, I usually build a single (spaced) coil: SS-316L, 28 AWG, 7 wraps, coil's diameter: 3.5 mm. This gives me about 0.8 ohms. My profile for Avocado24: 20W, medium preheat at 35W/0.5 s, 210C - that is 400-something F, I guess . That would be a MTL setup. If I wanted to chase some clouds with this wire/RTA, I would probably build 2 coils, 6-7 wraps, and open the air holes. But as a former pipe smoker I hardly ever inhale, not even MTL, and DL is totally out of question for me.
