I've messed around with a lot of coil combinations. The things I've found that work best for me are the simple ones. My OBS engine tank is running on .19 to .2 ohms with a dual coil setup of single strand 22 gauge wire wrapped on a 3.0 Coil Master post and firing at 55W. My Derringer clone dripper is at .3 ohms with dual pre wrapped Kanger coils and firing at 35W. The dripper almost seems to out cloud the tank even running 20W lower. I truly love the dripper but it's just not practical for travel so the tank is on most of the time. I'll give you a rare shot of my dripper on top of the Nano Steampunk though.
TLDR: Sometimes simple coils just work better than the fancy stuff. Here's a shot of my Nano Steampunk with the dripper on it.
