uh, 2-1. I mean, lots of days I'm good with just the ProVari, if I use anything else it's a mechanical, but I won't use more than the ProVari and a mechanical in the same day. Rarely I've just used a mechanical all day, but usually I get tired of cloud chasing and go back to the ProVari. Once I "pick" a mechanical for the day that's pretty much it, I don't tend to swap out for a different mechanical in the same day, although I might use a different one from one day to the next.
