Wow, this is an old thread, but I can post a reply to one of the questions, for the sake of archive searchers. First of all, nochaser, race stock skis are really fun, enjoy!
I ski the Volkl Racetigers. I got some "new old stock" skis a year ago, so they were new and unskied last year but the last of the actual Racetiger model, as opposed to the Speedwall, so had sat in a warehouse a couple years or so. When I got them the shop selling them said they were either the regular "race stock" or they could be the actual ones used on the World Cup. As it turns out, there is a racer (Patrick Biggs) who raced SL on the World Cup in the last couple years and he now coaches where we ski. I was on the lift with him, and he skis Volkl, so I quizzed him on this.
The consumer level "race stock" skis have the sidewall construction and the separate plate, unlike the regular production skis which are (or were) a cap construction. Turns out my skis are the consumer level "race stock" skis. They have a gold quality-control sticker on them just forward of the risers. On the true world cup ski, which he was skiing on, there was no quality control sticker. There are some extra numbers which are written on the sidewall, other than the usual serial number. On those skis, because the sidewalls get shaved down for tuning, the extra numbers on the sidewall also get written by hand on the tail of the skis.
He was telling me that I would probably not like the true world cup skis, and that he was thinking about getting something easier to ski. I'm a former recreational racer in my teens, and now in in mid 40's am fit 160 lbs and ski hard, really enjoying cranking hard turns and feeling the g's. For me, I'd say my race stocks are like skiing on scalpels when it's icy. They carve so cleanly like they are on rails. To really appreciate the skis though, you can't be a skier who wants to just cruise and be lazy and skid turns if you get tired. You have to be willing to put some energy into the skis, and they'll really reward you.
I would not say that my skis have a 10 for foregiveness. Maybe they are more forgiving than some other race stocks, I don't know, but they will put you into the back seat if you accidentally get back there a bit. If you are on the border between a skid and a carve in a turn, they will decide to try to carve cleanly unless you really tell them to skid. I think this may be less pronounced when I went from 0.5 to 1 degree base edge bevel. Or maybe I'm just more used to them.
I have not tried many other new race skis recently, but did demo one run on some Elan SLX's. I got the impression that those skis might not score quite as high for the precise perfect high-energy carve that I was getting out of my Volkl's, but if I wanted to ski smoothly in any radius, like taking a higher level instructor's exam, they'd be a easier ski to ski really nicely and cleanly at lower speeds with any size of turn.
