I'm assuming that drip tips come with some sort of stopper that you can use when you're not using it to keep it from leaking?
One last question (for now lol), say I want to try a new flavor. Would I just wait till I use up one of my carts and then refill it with the new juice? Or is it best to just use separate carts for each flavor?
I'm new to this but I think its a separate cart for each flavor. The clearomizers are nice and very easy to fill I have a few of those with different flavors in them. They don't seem to leak. But as also said the DCT tanks seem to be the easiest way to go. I fill mine every other day.
