I have to agree with nobolono. It all comes back to the awareness of the skier of the cause and effect of their input (movements) to their skis.
I got out on my new 168 (13m radius) K2 Mach Race slaloms last night and again this morning. Initially I was out of sync until I acepted that that they weren't going to ski like anything I'd ever been on, mush less adjust to me. So I tuned in, adapted and progressivly dialed in to them better with each sucessive run of experimentation and re-calibration of MY movements. I can now do anything on these I could do on any other ski, skid, pivot, spin, in addition to rip the arcs they were designed for. Are they less forgiving and require that I pay more attention? You bet! But for that very reason I will ski them more because of the learning oportunity there that would be missing on a more forgiving ski.
Beginners benifit from short forgiving skis but need to increment the length to keep stretching the precision and accuracy of their movements until they are on something that matches their seasonal skiing frequency and growth rate or suits where thay are happy to be.
If I get to the point that I can hear the grasshopper, I shall engevor to hear the flea...
