The Cham 97 has proved quite a hit for Dynastar so it's perhaps no surprise that the only change for this season is cosmetic (a change our tester approved of, incidentally).
Consequently you'll find that as in previous seasons it makes a great one quiver ski; it's totally at home in powder, crud and on the piste.
The performance in any one category is more competent and workmanlike than jaw-dropping, but that's perhaps only to be expected from a ski that's designed to do most things well and none badly.
If that's what you're looking for in your skis, then the Cham 97 is a good place to start.
