IC-160: 112/64/95 (15.3 m sidecut R in a 177) - The softest flex, lowest swing weight, and generally the quickest of this series of skis. Suitable for good intermediates and above.
IC-180: 116/65/101 (13.9 m) - The middle member of this seris in flex, total weight, and swing weight. Superb hard snow carving ski for advanced skiers, normal to lighter weight experts.
IC-200: 121/66/106 (12.7 m) - The most firm flex, highest swing weight, highest overall weight, and most stable ride of this series. Excellent medium R turns in smooth or rough hardpack. Doesn't do ultra-tight turns (in spite of its sidecut R) as easily as other skis because of its stiff flex, but this makes it handle rough conditions well. The 200 also does surprisingly well up to about 6" of powder or soft crud (from my personal experience). Most people consider this ski (especially in the longer lengths) only suitable for heavy, advanced skiers. I've got the first requirement nailed, not so sure about the 2nd, but this was my favorite ride of last season (in the 184). Actually, I own the xp-100 (123/68/108) which is almost the exact ski as the 200, but from the previous season.
IC-300: 109/64/94 (16.1 m) - Although close to the IC-160 in sidecut, the flex is *much* firmer than the 160, favoring much larger radius arcs than any of the other skis in this series, altho not quite in the 20-23 meter true GS range. Excellent carver in rough hardpack.

PS#2 - BTw, the comments I made above are my personal opinions, and are not taken from Peter's site, although we pretty much agree on everything about these particular skis.[ December 14, 2003, 11:16 PM: Message edited by: PhysicsMan ]
