Mostly what he said. You have to make a decision between stability at speed and beef (4x4), vs ease of initiation and wiggling through bumps (Tornado). I've only skied the Tornado and a relative of the 4x4 (the 11), but IMO the Tornado is surprisingly smooth in light crud or chop, very grippy, and of course light and easy to turn. The 11 was better at speed, the 4x4 will be even more so, and that taper allows a lot of different styles, so give it the edge in versatility on the backside. For me, though, had that typical Dynastar tip sensitivity in crud, which I don't like, even though the rest of the ski is very stable and smooth. The 4x4 may differ. It will be more demanding than the Tornado, want a heavier foot.
