Brad:? My three word thoughts on each ski you selected.
Dynastar legend 8000 2008? ?(good choice, better for western than eastern)
Dynastar 4800 2006-07 not so good at fast?? (8000 has gotten so versatile, don't see the advantage)
*Fischer RX 8? ? ? (excellent choice, especially for groomed slopes east or west up to boot top powder)
*K2 Apache Crossfire? 2006-8? each year better? (don't know much about it)
Volkl Tigershark 10 w/ps? ?(10 is better choice than 12, demo unless you know that you like Volkl feel. I don't).
Nordica Speed Machine mach 2/3
Volkl AC 30? 2008
Salomon x-wing tornado? 2007
Dynastar contact 11 2006-07 wider Not for old school style? (pretty advanced ski, I think, 9 is better choice)
*Dynastar contact 9 2006-07? intermediate level ski? ?(good choice)
*Head iSupershape Magnum 2008 good all round? ?(maybe a great compromise.? bit wider than RX8, still good on eastern hardpack)
*Head XRC 1400 Chip 2007? ? (maybe too much ski, magnum is better?)
Head monster i.m 72 srII? 2006-07? great all round? ?(great all around from three years back, magnum is better for heavier skiers I think)
Head monster 78 2008? wider, some off piste? ?(I use this for western trips, too wide for my eastern tastes. better than im72 I think)
I would add the Elan Magfire 10 from prior years.? Nice all around ski, I'm not up to date on this years equivalent models, and seems like they got wider and different reviews.? If I were to narrow your list to 3-4 skis it would be the Fischer Rx8 (66mm), Dynastar Contact 9 (68mm), Head supershape Magnum (71mm),? Elan Magfire 10 2005/06 (75mm),? Head monster iM78 (78mm),? Dynastar 8000 (79mm).
