I bought the hobo drifter and it's really good but I want to set it up for MTL with a pretty tight draw. I have never built an rda for MTL only my kayfun v4 so I really don't know what the best build would be. I was going to try a single coil 30 g 6 wrap but it seemed like it was really small. I was going to try dual coil 30 guage 10 wraps 3mm i.d. but I figured I would ask here before I started wasting wire cotton juice and time.
