I also understood the WC Air is not a "recreational" plate.
FWIW, I put the WC Air on my new P60 GS Race Stock. I didn't want to go with the "full-on" race plate (I understand its pretty burly) but did want to have a plate appropriate for the ski. I'll be using it for ski league and high performance recreational (hard snow) skiing. Maiden voyage will be this weekend.
I got mine from Lou's Skiing Performance Center in Calgary. Lou was very helpful and knowledgeable about VIST products and applications. PM me if you'd like his email and/or phone #.
