Awesome thanks, this is exactly what I needed to know.
So then what does 510 means exactly, I've heard it used to describe a lot of things, and people talking about things being or not being 510 compatible.
It actually comes down to the threads. If you look at the top of your Twist, you'll see it has screw threads on the outside and the inside. The outside ones are eGo threads, the inside ones are 510 threads. Like here:
(Pic shamelessly swiped from The Ocelot, one of my gurus from whom I learned so much.

).
Basically, really, it comes down to whether a widget will screw onto the battery or not. With an eGo battery, you get your choice. eGo threaded widgets or 510 threaded. They both work. There are other standards out there like the 808 (for example) that will not fit. As I said earlier, though, don't worry too much about it. If you want to buy some new widget, make sure it's "eGo" compatible. They'll say so if they are (and if they don't say so, don't do it

).
You'll pick the terms up soon enough. Well, enough to do what you want. There's still stuff people talk about that goes right over my head. Vaping has so freaking many options, nobody knows them all.
(Or I shouldn't say that. I have run into some real guru types around here that know so much, they're a little scary.

).
Also, can you drip with a Vivi Nova? I've heard different things.
Speaking of not everybody knowing everything, I dunno. Dripping ain't my area. It's supposed to be the ultimate vape so I must be doing it wrong when I've tried it. I usually just make a mess and burn my fingers.
(I am, however, an expert klutz)
I would think the answer is "no". Clearos and dripping? I've never heard of such a thing.
Dripping is a pretty simple idea really. You get an atomizer (which is basically just the heater widget all by itself) and drip the juice on the part that gets hot. Of course, you have a mouthpiece kinda thing you stick on the atomizer (they get pretty hot, I think e-juices vaporize around 200 degrees or something like that... I dunno exactly).
Me, I'm lazy. I use Vision clearos (not the Vivi but the "stardust" style CE5 types... they look like the CE4 in The Ocelot's pic up there but the coil heads are replaceable). Clearos are "squirt juice in, screw on battery, vape" simple. I like simple.
