Hi all. I'm tempted to do a quad coil on my kanger subox rba. 1 question though. The vid I seen on you tube picture quality wasn't that good but I would like to know if it's ok for the top and bottom coils to be touching. Wasn't to clear in the vid. Figuring top and bottoms can touch because they are wired into same posts either side. Quite new to this but I'm building some quality coils. Spot on what I'm aiming for. Like a kid in sweet shop. Building and swapping coils 2-3 times a day. Don't know if I want clouds or flavour. Hiesenburg on a 2.2 ohm 15 watts nice.
