I also like the thinner PV's. The 1000 mAh Twist is about the perfect size. The added length makes it more comfortable to hold. Aside from esthetics, I like to carry a few PV's with me, loaded with different flavors. I can easily scoop up a handful of eGo-sized PV's and drop them in a purse pocket, or put them in my pen cup while I'm at work, or at home going from room to room or outdoors. Carrying 3 Provaris would be awkward. In fact, if the voltage numbers on the Twist were readable without a magnifying glass, (and if it came in cool colors - like chartreuse) I'd say that I'd found my perfect PV.
