Wrong !!!Gator, they gave you bum info, man. The '05 Stormrider XL has a "sandwich-energy-race-system": wood core, double titanal-fiberglass. It does NOT have an ISO-core or a foam core. The '05 Stormrider AT has the ISO-core. The stuff coming out when drilling is some of the fiberglass.
Also, I think people recommending the XL in 174cm for most skiers are wrong, too. I have to agree with Highway Star that this forum is inappropriately biased towards short lengths. If you're a good skier and 165 lbs. plus, you should ski this bad boy in 184 or 194cm. Dom Perret's guys recommended this ski in the 194cm length for me and I think they should know better than anyone. People recommending this ski in 174cm, probably just can't handle it and aren't using it as designed.
