I'm back at 3.7 volts almost all the time. When I finish clogging a carto at 3.7 it just stops drawing, regardless of how hard I suck. At 6 volts it informs me that it's time for a new carto by spitting boiling hot liquid on my tongue. (Also, I definitely like long draws. Do that at 6V and the carto is dead long before it gets clogged.)
I'm not allowing myself to buy any new liquid until I vape more of what I have. I'm finally down to under 1.5 quarts. I bought 3 little bottles of something in November but, other than that, I haven't ordered a thing since August. A big reason is that I bought most of my liquid at 48mg. It lasts a lot longer when you are mixing it down to 6mg instead of 24mg. TV's caramel popcorn, peach cobbler and waffle will have permanent spots in my collection. I really, really want to try their cupcake as well. I got some Kick Bass Vapor Caramel Cappuccino from PIF. My first reaction was "yuck" followed by vaping the entire bottle like I was mainlining it. I really want to try their candy bar (Snickers) and Tootsie Rolly. And it looks like I'm going to have to try Deej's stuff too (despite the fact that I don't like champagne, the beverage.)
I might finally try a tank when Good Prophets gets theirs back in stock -- they're screw in so there's no fiddling with a needle.
And, to get back on topic, all of this is better on a Chuck. My Steampunk Chuck is practically glued to my hand. It's so perfectly balanced that my hand rarely hurts me. (When it does, a couple of hours with a Riva gives it a rest, but the Rivas are mostly being saved for stealth vaping situations.) Poor Junior, my Little Chuck, rarely gets a workout any longer, but he just can't compete with the balance or battery life of Omni, my big one.
