I tried the '99 Isosceles at the Grand Tour in Chicago. By the time I got to it, my palate (and brain) were pretty-well shot, but it still cut through all the "fog" and tasted very good.
I'd be surprised if it hit the "97" level as suggested above... but then... I've been surprised by Parker and Spectator many times before. My guess: 93-94; but a very nice wine at a relatively attractive price.
