I've had about two years on mine. For me, they've been almost bombproof. The bases seem to be better than any other skis, I've hit tons of rocks and have 2 core shots in 2 years. Just this fall, I started getting some edge cracks underfoot, which ripped out about an inch or two, which I got rounded off so it doesn't rip out anymore. Sucks, but I just use that ski so the edge is on the outside now. Like Seth said above, mine have gotten way more rockered, so they are flat camber underfoot with a lot of rocker. After two years, I still love to use them everywhere. Pretty lightweight, pretty durable in my opinion (two years of pretty heavy riding is awesome).
