I'm somewhat puzzled as to how you have found Proraso green to be slicker than MWF ... perhaps you've never truly managed to work da fat to its fullest potential.
The new reformulation 'Super Formula' is excellent, from my experience it takes a little more to get going but produces a very slick lather.
It's good, but is it as good as MWF? No, it's not, but few soaps are.
