Welcome to ECF!
I currently am using a typical Tootle-Puffers set-up. A clouper mini and a Kangertech mini. I use their 1.2Ω or 1.5Ω (ohm) coils. I always vape at 18.4 watts. I get loads of vapor and enjoy the heck out of it. I can make my own coils, but, I am just a little lazy and a pre-made coil with that Ω's lasts over a month. I keep four set-ups like this always charged and ready. I make my own 20mg/ml juice, and it has never gunked up the coils.
