For one, I've been a bit confused seeing that the ego twists are always listed as ego-c twist's most of the time, because I thought the twists were just a build of their own like the T's and the C's, so you can shed some light on that if you want. But my real question was, what's the difference between and ego(c or whatever) twist and an ego ultra twist? I bought a kit from vapor beast for an ego ultra twist, thinking that the word "ultra" was being used in a marketing sense, like implying this is some "ultra" kit (which it was pretty awesome IMO) but then I was browsing the interwebs and apparently it's different. So, that being said, what is different exactly?
