I have been trying to figure that out since I started. I get a mouth full of
juice with just about everything clearomizer system that I use. I use Nova tanks now because the Starlights leak like a sieve no matter what, so I found that if I wait a few seconds between drags, I don't have the juice problems as much. If I get a mouth full of juice now, I take off the drip tip right away and clean it with a q-tip or a kleenex. When I add juice to the tank, I clean the top of the tank that screws off and I stick a q-tip in the atty head to pick up the excess. I bought some knuckle head drip tips to use when I direct drip and so far, they keep the juice out of my mouth. Good luck and let me know if you find something that works.
