Evods, Leaks, and juice thickness

[piggy]

This is what I found so far. My high VG juice (don't remember how much VG, but it's more than 20pg/80vg) does not leak when I take out one wick. Anything less than 30/70 I get a center hole leak when its 1/3 or less full. So I'm thinking, 20/80 or higher remove one wick, 20/80 or less leave both in. Anyone else with similar experiences?

I get leaks with 100% vg when it's getting low... I either ADD a flavor wick if I have some or redo them entirely with 30-40 strands of cheesecloth thread

Rule of thumb: if you change thickness of liquids add flavor wicks. If you get dry hits, remove wicks.
