I have skated on 7/16” most of this year, as I was previously sliding sideways on 1/2”. As I’ve developed better edge control from taking lessons, I thought I’d try 1/2” this evening. It went well, I had just as much control, but it seemed to be a bit less effort as the edges dig in less, and maybe I had less tendency to catch an edge. So I think I will stick with it, until the ice gets hard, then I might go back down. I’m about 11 stone 7 pounds, so not heavy. They say shallow hollows wear more slowly too, as the edges are less narrow.
