You guys should totally post a "rate my trade" thread in the ACF.
Big Jim, you got a lot of stuff I have in that trade. Thus far, I haven't been a big fan of caramel vapes, in fact I just traded 30mls of Bluemist Caramel Tobacco on ECF last weekend for some FSUSA Hypnotic Mist that should arrive any day now. The Massive Chocolate Mint is a dead ringer for Thin Mints and has a great TH and vapor production. Likewise, the Irish Cream has a very true flavor of Bailey's and also produces great TH and VP. Alien Visions juices are so damned tasty, the only negative to them are that they're 100% VG, so the TH is often lacking, forcing me to mix them with thinner PG juices. I've had some pretty great results doing an 80/20 or 75/25 mix of Boba's Bounty with VaporStation Tampa or VS4, though. The MCM and Irish Cream, though, are two that need no help at 24mg. Throat hit is killer, even at 100% VG.
Also, in reading about mods and Ohm's law, and all the stuff Rovers is talking about, it's become readily apparent to me that the "current" produced by your PV/atty/carto combination is what defines the "oomph" you get in TH and VP. It's really very simple to calculate
Voltage/resistance = current.
All you need is the voltage of your PV, and the resistance of your atomizer/cartomizer. You can measure this yourself with a meter if you like, or just take the standard averages. The Bloog MaxxFusion battery starts at 4.2V, drops quickly to 3.7, and remains there for about the life of the battery. The V4L batteries start at 3.7, drop to 3.6, and then in my experience, drop to 3.2-3.4 before petering out. Different cartomizers have different resistances, as Rovers mentioned earlier. The WOW cartos from V4L ring in at an average of 2.6, The MaxxFusions at 2.5, and the V4L Cools at around 3.0. They're not perfectly consistent, though - one side effect of Chinese manufacturing, in the opinion of many. Leaford at Bloog has mentioned that it's one of his biggest headaches, trying to ensure that the cartos offer as consistent a resistance as possible. Even with his QC, a box of 5 Maxx Fusions that someone measured of late registered a 2.2, 2.4, 2.5, 2.5, 2.6 in the same box. LR (low resistance) cartos might be more in the sub 2.0 range, and were designed to get more amps out of batteries with 3-4V of power. With the current generation of batteries, though, as Rover said - they're basically obsolete. Anyway, to get your "current", you just plug these numbers in. If I use the MF battery with the MF carto, I'm getting, on average :
3.7 volts (battery voltage rating) / 2.5 ohm resistance (carto resistance) =
1.48 amps of current.
That 1.48 is the number that effectively quantifies the "power" of the vaping experience, mainly due to the heat with which the juice is being vaporized. The hotter the atty, the hotter the smoke, and the more vapor that will be produced per blast. Most variable voltage mods have a cut off at around 1.9-2.2 amps, anything beyond that and you risk frying the atomizer, plus the taste of the resulting vapor will be "burnt" and unpleasantly harsh. So, if you have a variable voltage mod with a threaded 808 attachment, you could screw in a MaxxFusion carto and crank the voltage up above the 3.7 you're getting from your 808 auto battery. Using the low end of the cut-off range, you simply invert the equation.
X volts / 2.5 ohm resistance = 1.9 amps of current. Simple pre-algebra then to solve for x : multiply both sides of the equation by 2.5 and x = 4.75. So, theoretically, you could crank the voltage on your VV mod up to about 4.7-4.8 without melting the carto or getting a burnt flavor using a MaxxFusion cart. If you wanted to be safe, knowing some only offer 2.2 ohms resistance, you could dial that down to 4.2 (just replace the 2.5 ohms with 2.2 in the equation above.) With a 3.0 ohm Cool Cart, you could go up to 5.7V. If you had a Cool Cart on there then, you'd know that 3.6V would give you an experience similar to using a standard Vapor King 808 battery, and that ~5.7V is your effective "ceiling." Then, just mess with it within that range until you find the "sweet spot" for you that provides the vapor, flavor and TH you're looking for.
