any 510 drip tip will work. I think the 50/50 juice will do ok. It performs very well with 70/30. This is not one of my favorites, but it is pretty good. My primary complaints are 1) If it is going to be that big, I would rather have more juice capacity. Lots of wasted space in the top of it. and 2) I seemed to get more juice in the mouth with this than with the vivi nova. The 4 wicks do work very well, though.
