NONE Betaracer answered this a while ago, there is no differnce between this years 2002 and last years 2001 9.16 race slalom ski. this also applies the the 9.20 race ski too. Cosmetics changed a little but thats it.
I really dont no exactly what the cosmetic changes are but do you really care? I do know they look almost the same, very minor changes, in other words unless you had them side by side most wouldnt notice they were differnt at all.
