The Cham 97 is available in lengths of 166, 172, 178 and 184 (my length) cm. For my taste (I'm 186 cm, 83 kg and a friend of a faster riding style) there could definitely be a few more centimeters in length. But in the steep couloirs around Chamonix you probably won't need them ... Larger models (190 cm) are available in the Cham 107 and Cham 117 brothers. Perhaps this is just a feeling of habit that will wear off after more intensive use of the skis. According to the manufacturer, the radius is 15 meters for all lengths. As the weight of the ski (2.3 kg per ski) is of secondary importance to me and the downhill performance is what counts most, I opted for the "more stable" version. For all touring freaks, there is a much lighter high-mountain version (1.8 kg/ski).
I first made friends with the ski on the piste (grippy), where it impressed me with its amazing precision and maneuverability. Only the "fluttering" nose took a little getting used to, but this is difficult to change with a rocker tip. The ski is therefore suitable for more than just crossing the piste from one powder spot to the next.
But now to the actual field of action of the Cham 97: In powder, the rocker tip provides plenty of lift, which is additionally supported by the pintail. The sand-width construction (wood core, fiberglass, titanal coatings) makes the ski extremely stable, both in rough terrain and on bigturns.
