Pros: Easy to ski in many conditions, inspiring
Cons: A little expensive, maybe less suitable for lighter finesse skiers
The Powerline is a beefier version of the XW Tornado TI--all round skis classified as 70/30 expert skis by Salomon. I have skied them in different conditions (from ice to 12 inches of powder) and they just go. Ploughs through crud without hick ups, good bite on icy steeps, quick and maneuverable in the forest and very stable in high speed GS turns. Easy to ski slow as well, which can be of importance if you like me, have kids. Would imagine it could be a valuable characteristic for ski instructors and patrollers as well. I've skied Rossignol Bandit SC80's and prior to that long skis (Fischer SC4 in 195). I've rented and skied various Elan and Head skis as well, but the Powerlines just blew them away. The Salomon skis are just so much quicker, grippier and more inspiring.
After 30 years of skiing they made me a clearly better skier over day (I'm 40 years old, 5 ft 9-10" and weigh 186 lb). I ski them in 173. Very potent do-it-all skis for Europe and USA East and Midwest. I'm not familiar with the conditions out West, but would be surprised if they didn't work there as well, short of deep powder.
