Mike, I first did this on stock heads and it was so good I almost didn't even think about rebuilding, I bought four vivi novas and had 12 heads. Figured why rebuild when the over wick makes them so good. Finally curiosity won and I rebuilt one this way and wow now I am a fanatic of this setup and it really doesn't matter what wick is in the coil, the batten over wick averages every thing out and makes it better.
BJ43 - I get what you are saying that the "batten over the wick averages everything out", After experiencing an almost perfect vape on your configuration (I used a coiled 1/0 cotton wick and the cotton batting) with a favorite juice that has been through attys, cartos (LR/HR, Dual), Silica wick Smoktech Vivi, SS mesh and cotton Smoktech Vivi, silica wick Viva Nova, SS Vivi Nova, cotton wick/cheesesloth Vivi Nova etc...
I want to see if you could describe in your own words the effect that you are tasting/feeling and generally experiencing vs these other mods?
While I am very interested to learn about your experiences, because you probably have this thing so better tuned than I have, I wanted to share a couple of comparative thoughts.
In general, not compared to all other combinations, your config provided me a kicka$$ balance of:
1) a very smooth taste and feel vape (no highs, no lows, just consistency)
2) no dry hits (the cotton batten provide a superior fast and supplemental wicking source to the primary coil wick)
3) fullness ( I dont know how to express this, but the body of the vape gets thicker. When I get the coils to the right heat, sometimes I feel the draw pressure increase and the vape get almost gooey (?)
4) Subtle flavors in the Juice that are non-existence or seriously muted in other set ups really shine through. ( I am using a 100% VG NET)
5) The vap always feel moist, not thick like the above, more like a high humidity air quality, like say being in the Islands?
Just for keeping things even , I have gotten great results on these other mods...especially SS mesh. But in combination, especially the smoothness of Cotton and the simplicity, this set up really shines. Just some thoughts, very interested to hear yours (or others).
