Seems like it should work, suggest that the "frontside/backside" be altered a bit to: "Predominately groomed," "Predominately ungroomed," My rationale is that many frontsides (if you mean lift served) have both groomed and trees and such that are mostly ungroomed and/or bumps. Lot of eastern skiing is like this, as well as places out west like Mammoth or Steamboat. Backside means various things to various people; I always think of Vail, where the "back bowls" are lift served and many have groomed centers, not to mention lodges, plus a bunch of ungroomed that gets cut up quickly. But for others, "backside" means deeper powder, or even near resort hiking/skinning terrain (eg, sidebounds). You could do nicely on the backside of Vail the day after a storm with midfats. Not so Jackson Hole.
Since the point is that skis are oriented toward snow conditions, not which side of the mountain you're on, might be useful to stick with the snow.
Agree with the revision away from "big mountain/all mountain" etc. since everyone thinks they a) have skis that rock everywhere, and b) ski on/want to ski on big mountains or on skis that will reduce said moutains to whimpering.
As far as the star ratings, all are useful to me except "performance," which can mean anything, and "durability," which will vary according to the skier. For a good reference IMO, look at Ski Press World's numerical ratings. You wouldn't need so many, but I really like having categories like "Ease of initiation," or "Stability," not to mention "Forgiveness." And I find "Edge grip" to be highly relevant for any ski that you use with a lift. You may not use your edges in powder, but you sure do getting to it and back again unless you skin for your turns. OTOH, it's a misnomer, in that you're less concerned about sharpness (which will be largely a function of tuning) than how easily you can deploy your edges, how predictable they are, what kind of feedback they give you. Would rather be on a very dull pair of Blizzards than a very sharp pair of K2's...()
