I haven't skied their park skis, but I'm currently on their Agent 100s as a day to day directional touring ski here in Scotland. As far as durability goes, they seem pretty solid, I've only managed to put a single core shot in them. But that was my fault, I knew as soon as I touched down on the rock that it was a core shot, I landed pretty much straight on a rock right below the boot coming off ~6ft of air. There's been occasions since then when I've thought I'd core shotted them, but then I stopped and had a look at my bases, and they were fine.
