Building a higher resistance coil like a 2.2 ohm coil using 30ga wire, then vaping it with your kayfun clone would be my suggestion. As it relates to dripping, I can't take the TH off my 18mg juice no matter what I do. I just bought a new set of 6mg juices to use with my RDA's.
The other thing you can do is to mix your higher nic juices with a lower nic or 0 nic juice to dilute it. Heck, you might even come up with a flavor combination that is really good, then share. I had less than 2ml of this really tasty pineapple, mango, hint of menthol flavor (Standard Vape, G35) left and was about to leave the house for the day. I ended up topping off my kayfun with ecto cooler just to see what it would taste like, ended up really liking it. I actually bought another bottle of the G35 juice just to mix with the ecto cooler now. In my case, they were both 18mg juices and I didn't do it to dilute, but the concept is there and seems sound.
