#500 was a massive improvement over #400 and I use 100% VG from Mount baker (syrup) and dilute it myself with a sizable amount of distilled water. Probably 25-35%. I've never actually measured it out. I do a very hollow wick in my RSST, wrap a microcoil around it, using 26 GA right now, 13 wraps, and crank up the voltage.
The microcoil really chucks the vapor. The genesis atty is the most pleasurable I've ever had, and I have a Protank II, Russian 91% and a whole host of other attys. I even have an IBTanks carto tank, which is gorgeous, but carto's gum up quick with high VG.
After I make my hollow wick, I usually put another sleeve of mesh inside of the original wick. Restricts down the hollowness of the wick more. I leave my fill cap on my Pyrex RSST on and it chucks the vapor like none other. Picture time!
That's my current build. 26 gauge kanthal microcoil. 12 or 13 wraps, 2.2 ohms. Firing it at 5.4 volts which is madness.
Same build fired up
DIY reducer I built for my top cap. Beer can folded just right, and filled in the gaps with cotton. Warmed up the vape and improved the flavor by a fair margin. Did not cut off any air flow
My old build with 28 gauge. Nice even firing and an incredible amount of heat being pumped to that wick. This one started at 2.5 ohms and climbed to 2.9 ohms in the span of a month. I think it's just the nature of kanthal as it wears out or something. I ran that one at 5.5-5.8 volts and cranked it up to 6.0 on occasion
The genesis seems to roll better with softer flavored juices like caramel, vanilla or banana. The blueberry flavor I have for it is rather harsh. Flavorful, but really thumps your lungs and is almost painful at times. Not so with the softer flavors.
What kind of genesis did you get? And what device are you using it on?
People may look down on me, but I order all my supplies from eBay honestly. I've been using eBay for most of my online purchases and am just comfortable with it. I can get 100' of (pick a gauge) kanthal for under 10 bucks. I got three 6"X6" sheets of #500 mesh for about 9 bucks.
If your going to microcoil, or are using (and are comfortable with) a mechanical mod, go with 28 gauge. If you are just doing standard 3/4 or 4/5 wraps, go with 32 gauge. That's what I learned on. 32 gauge won't microcoil very well because anywhere beyond 5 wraps or so and your ohms climb too high to be reasonable
