I normally ski the Supersonics (167cm) but recently demoed these cheater slalom skis at Killington:
Blizzard Magnesium SLR (160 cm): Fairly stiff, precise, and demanding. Need to stay right on them, they punish the briefest tendency to get in the backseat. A one trick pony, they only want to make very short turns. Felt lilke a real race ski to me. They are fast and held the best on ice, but were probably the least fun. Held the steep ice on Outer Limits most efficiently. Didn't find many moguls that day.
Volkl Racetiger Speedwall (160 cm): Awesome ski, real carving machines. Also more demanding than the Supersonics, but less so than the SLRs. They obviously shine in short radius turns, but could easily swing nice GS turns as well while staying reasonably stable. Less demanding and more versatile than the SLRs, but still a good workout if you're going to ski these hard all day. They also have incredible rebound energy. On soft semigroomed snow on Superstar I felt like they were springing me from turn to turn, in a good way. But you do need to stay on top of them. Great in moguls. Thinking of buying a pair if I can get a good deal.
Blizzard G Force Supersonic (167 cm): These felt slightly dead the 1st run after the Volkls, but with some (personal) adjustment they came to life. They had not been tuned as recently which was part of the problem. Definitely the most versatile of the three. Happy in any turn shape, fairly stable at speed, great in crud and bumps. They're kind of like a blank canvas. And way more relaxing than the other two. But probably an inferior carver, and less energetic. They don't punish little mistakes. These have been my daily eastern ski for 2 years.
About me: 45 years old, 145 lbs, fairly strong skier, raced in high school and college. (Back in the Dark Ages!)
About the conditions: mostly firm, groomed, and steep. Mainly skied Superstar, Ovation, Cascade, Wildfire, Outer Limits, Bearclaw
About the skis: First 2 were demoed from Northern Ski Works in Luddlow. They had a real nice tune on them. 3rd were mine.
Just thought I'd share, since I rarely see anyone review skis in this category. Apologies if I'm not following the correct format.
