It was between the Cthulhu and the Limitless for me. I feel like the Limitless would give the Cthulhu a run for its money. I'm pretty sure you could fit more wire in my tank but the Limitless would do more with less. If you put a little coil in the Cthulhu with the chamber as large as it is, it would be underwhelming.
The Cthulhu wins the single coil battle imo. There's no posts in the way so you're only limited by the size of the chamber.
The only reason I picked the Cthulhu is because I like RTAs more than dripper because of the chimney. Still wish I had one though.
Here's my first single coil build...I used some twisted wire I had lying around. It doesn't vape well but this was just an experiment to see just how big I could go. I wrapped it around a screw, no idea what size so I took a picture for scale.
I just took ten long pulls at 80w with a 100w/.25 second preheat. No dry hits but it needs some clapton for sure.
