There's one thing to consider, and I guess Tdk6 is talking exactly about this aspect. Thing is, ski companies have two different production lines. One is normal production line, and the other is racing service. Skis for World cup racers are not made in normal production line (except for Elan, as 2 years ago, they put racing service press machine into production... yeah no comment needed). So availability of normal store skis (or even lower quality (or whatever proper word is) racing skis) is unrelated to availability and production of race skis for WC racers. Most of these things are really done in same place (WC race service concerned). Rossignol and Dynastar are made at same place, and are basically same skis. Atomic and Salomon are same (also goes for Rossi/Lange and Atomic/Salomon boots). I have no idea for Nordica/Blizzard, but I doubt it would be much different
Another issue are ski pools. Sure sometimes it's worth paying to ski pools at different ski federations twice, as even though company is under same roof, Atomic is paying their share to si pools, and Salomon is paying their share (that's why for example you have Rossi with Austrians and no Dynastar). But sometimes it's not, especially when times get tougher. Nordica did cut whole bunch of their racing service budget last season already, and signed pretty big deal with Neureuther, so they basically fired everyone else except Dopfer (they completely removed race women line, and told Rebensburg to go). So will Blizzard stay? Most likely, as for huge majority of skis, being present in racing is still best marketing possible. Will it be in all pools, probably not, they might withdraw themself from some pools and enter some new ones, but that's pretty much same with every other company. Fischer was long in Slovenian pool, but it's not anymore (it's still in nordic, but not alpine), on the other side, Atomic came. Things change, always did always will :)
Excellent information here. Its even more complicated than I thaught. And its all about business and money. Thank you for posting.
