Me: 27, 6'0", 200lbs, solid level 7, athletic, like to ski groomers aggressively, not much on bumps or trees, love open bowl skiing when I can get it, starting to venture into the steep stuff (getting comfortable on open, double-black terrain).
Of the skis you've mentioned, I've only been on the Metron M9 (2006, 171cm). A ski which I enjoyed immensely. I had never been on a ski with as short a turn radius (13.5m), coming from a 180 C9 (17m). It definitely prefers the modern carving technique, but they allow you to swing them and skid them as well. I thought they might be too soft for me, especially after trying the Volkl AC4 (170) and the K2 Apache Recon (167) before them, but that wasn't the case at all. I liked them so much that I jumped on eBay and ordered a pair.
Due to their fairly dramatic sidecut, they like to be on edge. A very large sweetspot, and their tails aren't punishingly stiff. I don't typically get in the backseat, but I did so on purpose as a test and didn't get bucked. They don't like to be skied flat, but they will tolerate it at moderate speeds. I don't care much for bumps, so I didn't test their ability there. The snow in Breckenridge was nice and soft, so I can't speak for their grip on ice. I hope to be able to report back on that aspect soon, as I expect to receive my pair in the next few days, and that's all we have in Indiana is manmade ice or slush (rarely an in-between). Expect a workout, however. With the short radius and the fact that they like to be on edge, your legs will tire perhaps more quickly than what they're used to. That's not necessarily a bad thing though. We can ALL use a little bit more exercise!
