I got my package today from GV. 3 ViVi Nova's. Some spare heads and a couple more eGo Twists.

Filled up the first ViVi with Bananas Foster from Juicy Vapor and all I can say is WOW. Great flavor and tons of vapor. 2.4 head at 4.0 volts.

Reporting back. Briar, I cut the wick on my 2.4ohm head... I got flavor loss, not improvement. Not much flavor loss but enough to notice. Maybe what we've been discussing about different mixes wicking different ways is very very accurate.

Youd think mostly 100% vg juice wouldnt wick better flavor with longer wicks but in my case it does.

Sev, I saw that inset rim inside the cap but my drip tip does sit all the way flush. You have to literally force the drip tip in hard but it does go flush with the cap.

Much thanx, your very kind. I take a untreated 4 X 4, and drill holes using "forstner" bits, of verying depths (A drill press, is a must). One is a 3 "step" and the other is a 2 "step" My profile "Album pics" shows the full view..Its quit long...

Thank you - my husband said he will have no problem doing this for me - great idea!

You know, we need to keep notes on this stuff - will come in useful, eventually, if we can systematize it.

Maybe - and that's just a theory, mind you, I'd have to go look up the formulas for this since it's been 30 years - maybe the higher viscosity of VG results in stronger capillary action up to a point? I can see how shorter wicks might possibly reduce wickability if this is true - but why would it reduce flavor?

It's got to have something to do with juice viscosity/consistency... And, possibly, the kind of flavors being used - after all, different flavorants will have different size molecules, and how well flavor molecules stay within the medium will depend on both the size of the flavorant molecule and the size and bonding of the medium molecules. And the filtering effect will depend on the materials properties of the wicks in addition to those things.

Yes, I overcomplicate things. If we keep track, we can figure this out experimentally. :D

How much of the wick did you cut off buffaloguy? Does anyone think you can cut them too short? I don't mind if i have to turn it over or so to keep it vaping good. Let you know the results in a few minutes :)

I think the only way you can cut them too too short is if they are no longer touching the walls of the tank... However, I did go somewhat conservatively on this procedure, so mine are a bit longer than that. I should have measured them, durn it...

Well my mixes in general all 100%vg nic + flavoring (either pg or alcohol based, sometimes both. Not sure I can mention whos flavorings here in gv's thread) + distilled water. I work mainly in tobaccos and some fruit/dessert type vapes but for the most part I end up around 80%vg/20% everything else. Tobaccos for me end up having a higher dw content.

I cut the wicks so that they ran down the side of the tank just a smidge, maybe like 1/8" down the sides.

With full wicks I never had to tilt or roll at all. It just worked. Juice seemed to draw up fine thru the wicks. Ive yet to run this tank below the level where the wicks are yet but I imagine Ill have to roll it at some point.

I wonder if its the dw content that makes a difference in my juices helping to carry the flavor better and allow for better wicking? Just a wild guess. Im certainly no chemist. I know for a fact whenever I have a juice that was stubborn as far as wicking adding dw solves that problem every single time and doesnt effect flavor. A few drops of dw in a juice goes a long way. I rarely have to do that anymore tho. Ive found the ratios that work for most vg juice in pretty much any tank, carto, clearo etc. etc. Its always 75%-80%VG and the rest flv, dw, etc.

Maybe dw makes a difference as far as carrying flavor goes - it's just a guess, and I'm no chemist either, but we are just looking for trends to this, because so far it's been like some kind of weird alchemy as to what works for whom when, and it would be nice to find out how, so in the future we could at least predict something... :D

You see how some folks love the short wicks and some not so much, and I keep wondering why. It's not just a matter of taste, you know? Flavor strength and wicking are not subjective issues.

Also, I apparently have a different vaping style than you. I tilt all the time, in fact I prefer to hold my PV close to horizontal, and that makes a huge difference. My wicks are never out of the juice.
