Many many years ago, before I ever took a ski lesson, but after I had been skiing for a few years, I decided it was time to replace my Dynastar 185cm fibreglass
: GS I think skis; they just couldn't handle speed.
I was told the same thing: "Racing" skis are for racers and accomplished experts only, unless you are on a race team you won't want these skis.
I didn't know about all that, but I did know that when ever I got on a pair of skis, as soon as I got it cranked up to speed I may as well have been wearing plastick bags over my boots for all the control I could extract from them, until I demoed my 208cm Kästle RX12 National Team SG skis. Being rather headstrong, I ignored advice and got the SG racing skis.
There was a steep learning curve. I did fall a few times on these skis whereas I would not have fallen on lesser skis, mostly due to catching edges and inadvertantly havingthe tails steer me faster than I could keep up. These skis were nothing special at sub 20 mph speeds. In fact I could (and still can) only bend one ski at a time into a tight turn at those speeds. But they were an absolute dream at high speeds, especially on hard snow. Since high-speed skiing was what I was into, I was very happy with them. I am very glad I got them and I still love to take them out and let them rip.
Some things have changed since then. The biggest change is the "shaped ski". I still have to try out a modern SL "racing" shaped ski, but have been on a couple of modern high performance models (RX8 9S), and recently tried out a yardsale Fischer SL racing ski from a bygone age.
The old-style SL race ski had been "tuned" at my local shop, which means that they ruined the tune of the ski, making the edges dull at the tip and tail. It took me a while to figure out why they would do this to a ski, but it is very relavant to the present conversation, so please bear with me. This ski was absolutly terrible as a recreation ski for someone who likes to carve turns. It would only carve at speeds too high to be safe considering the crowded conditions at most ski hills. It's ice grip was also pretty much nonexistent.
On the other hand, it could handle skidded and pivotted turns just fine.
Top-end shaped skis will carve just fine, but don't really like to be skidded. This behaviour is more noticeable the higher up you go.
Whereas old race skis can be detuned to become good skidding and pivoting skis that work at any speed or left sharp to be good high-speed only carving skis, I strongly suspect new shaped slalom skis will only work well at carving speeds at high (for slalom) speeds; they will not be good at skidding turns; they will not be good at pivot turns.
Bottom line. If you carve turns and don't really care too much about slow speed performance go for the Stockli SL, but if you like to pivot and skid turns, hunt a little lower on the food chain or go to a yardsale and spend ten bucks.
