I've been playing around with The Big Dripper I finally got from Grand Vapour Station and I'm definitely loving this thing but I'm still trying to find the best coil set up for it. I've currently got a dual coil in it (6 wraps on each side around a 5/64) sitting at .55 ohms. I've been running it on my rDNA but I feel like the vapour production could be better. Anyone out there have their own big dripper and feel pretty good about the vapour production they're getting off it? Keep in mind I'd be running it between 30 and 40 watts. Any tips about wrapping style or coil height in the cup or whatever else anyone can think of would be welcome feedback.
