pgeorgan 46 Report post Posted October 1, 2020 Tried out a Zup S. My regular steel is a Quad 0. These are night and day different. I did not like Zup S whatsoever. Zero mobility. Looking at how the various radii, I suspect a Zup XS might be closer in similarity to a Quad 0, but I probably won't try it as I can already tell I'm not going to like it more than the Quad.
