Okay, for those who have issues with excessive condensation and juice-in-the-mouth syndrome, I think I may have solved the issue.
The only problem is, I don't quite know how.
This is my Fluxomizer tank mod. I'm using that same tank right now. Still works great, and the only change that I have made to it outside of that video is that I'm now using 2 of the middle O-rings stacked instead of one: The lower groove-side down over the cup as many of us have already done, and the other groove-side up. The tube length I cut and its positioning in my tank mod has made for about a 2/3mm gap or so between the bottom of my drip tip and the top seal. I haven't had a single juice in the mouth incident yet. I haven't even had a
hint of juice in the mouth, not even a thin sheen of condensation at the mouth of the drip tip transferring to my lips. I don't know why, but here is what I do know:
1. The top groove-side up seal does trap some condensation and liquid in the groove.
2. The gap between the top seal and my drip tip is small enough to trap condensation as it enters, but as the liquid pools, its surface tension keeps it trapped there. Any stray condensation from the air channel that passes this gap seems to flow into there and doesn't come back out, or if it does, it just drops back into the cup/coil.
3. Bearing in mind that I've done the donut mod to both seals, so the air channel from the cup on out is wide.
4. When I remove the seals for filling they're pretty juicy. My drip tip, however, isn't, except along the bottom where the juice gets trapped between that and the seals.
So, make of that what you will, but it seems as though somewhere in there is the secret to solving the juice-in-the-mouth problem.
