We wrapped up the USSA season this year about two weeks ago. My son did great on the Rossi R-11s, usually in the top 1/3 or so of the J2's. The details ain’t important, but he went back to the Head GS skis for the last two weeks of the season, including the championship, and did not fare nearly as well. In fact, I beat him at NASTAR during this change at least twice. This weekend he put the R-11’s back on and he beat me.
As a side note, I started using the R-11s when my son switched back to the Heads. It is by far the best ski that I have every used, especially on ice. This is the first ski that I have used where I can consistently engage the entire edge on ice. In fact they are so “grippy” that I have to be very careful when making a fast slide stop, for fear of engaging too much edge and overpowering my legs.
I’ve re-read through the earlier recommendations in this thread and again I say thank y’all for your thoughts and information. It looks like Vokl’s or Rossi’s are the way to go for my son. The decision is likely to come down to price, and since I ski for a local shop’s team that carries Rossi they’ll probably give me the wholesale price.
Since I’m not sure what the 2010 USSA regs and enforcement will be I’ll obviously wait until next October or so to make the purchase
