I only need my edges for ice, so the 3 side might be handy. We had 2 months of lovely ice and I dreamed of edges. now the ice is back in the mornings, and I'm dreaming of edges again. They've done well though. I skiied on these all last season (I ski all day every day), and all this season, and they are still factory (gouged, blunted, hacksawed albeit).
