Maybe I should rephrase what I said about them being slow. The v-6 and7 are a hell of a lot harder to turn than my rubiks and eastsheen 5x5s. After 3 solves on my v-5, its already gotten a lot faster. I've solved the v-7 twice and it hurts to try to use 1 finger to spin a side (and impossible to do fingertricks). It's a little easier to turn the v-6 sides but due to the mechanism on the inside, it's just as bad. So I think I'm going to solve them a bunch today and tomorrow and then lube and mod them tomorrow night or wednesday.
