Hey, I love you too man
Yeah, "Twist" = joyetech eGo-C Twist - the first eGo-class variable-voltage device to come on the scene, a few months ago. Prior to that, going with variable voltage pretty much meant shelling out $60-$200 on a "fancier" device like an Apollo SS VTube, a Buzz Pro 2, a ProVari, a Smoktech VMax, or the like.
Now, you can get the exact same actual vape in a more affordable, more transportable, stealthier, don't care-as-much-if-I-lose-it-or-break-it "form factor"; namely, and eGo-class battery.
I say "exact same actual vape" because ... well, just that - the "actual" vape will be exactly the same, attachment for attachment, on a Twist or on a 24-karat gold plated ProVari, but the latter will give you better battery life, a digital readout, a device that might last your entire life, and has a "wow" factor that's off the charts. But the actual vape will be the exact same, as long as you're staying within the amp limit of the device by using a sensible resistance of coil. On the Twist, that's anywhere between about a 1.8-2 ohm and a 3.0 ohm single coil IMO. It has about a 2.5 amp limit, which is just fine for about anything except trying to push a 1.5 ohm dual coil at high watts.
Volts are volts, ohms are ohms, and amps are amps. The electrons flowing through the coil don't know their device of origin.
Why is it called the eGo-C Twist? Good question. It has to do with the Joyetech eGo-C tank system, but the two need not be related in any way. The Ego-C Twist can be used with a huge array of attachments. It's "just" an eGo-class variable voltage battery. The only one (AFAIK), until the arrival of the kGo VV, which IMO still has a few bugs to work out. For now, just get the Twist and some Vivi's, and vape.

If you want a bottom feeder, you can now get VV in a Reo; both the Woodville and the Grand come in VV. But I'd still get the Twists (first), because they're more versatile IMO. Good for just about any occasion, location, or purpose. (If you get invited to a State Dinner or an audience with the Queen, look hard at that 24K gold ProVari - they are nice - (even the non-gold ones).
Now my wife wants the ProVari.....and she don't vape.
