is there a difference between the 2010 and 2011 Coomback? What do they mean when they say (flat)?

Hay I love mine !! I ski all kind of stuff. I'm a Patroller in Wisconsin and Ski Vail,Jackson,Alta Snowbird.Small cliffs trees and steeps Saturday 12/11/10 ,Last week end they killed in Chest deep drifts and knee deep blower powder of the back at Vail.They ski the Groomers great also because they are Rocked in the front. I love big GS turns on groomed and they are great. I've Skied 1080 Guns before and these bring them to there knees. I have the Marker Dukes and skins to match. I have done some 20-30 min hikes Side country type stuff and feel I have the right Ski for the all around stuff I Ski. I'm 5'7'' 180 lb's and ski the 174's 17

The new 2010-2011 Coomback has a new snophobic top sheet that keeps snow from sticking to the top sheet when touring....you can wax it too...to make it even more SNOPHOBIC!!!........The new model now has custom pre cut skins that fit the Coomback perfectly as well as the other Adventure Series skis..........as far as the construction of the 2010-2011 Coomback compared to the 2009-2010, I believe everything is still the same...but you might want to wait to hear from the Backcountry experts on the actual construction differences..... I have skied previous models of the Coomba/Coomback and they are sweeet!!!!....totally all mountain, all conditions ski........one quiver ski for most...........The 2009-2010 model is no longer available on BC so you might have to go for the new model at $649.95..........depending on your size and ability....but I ski the 181.....nice...... *I can definitely answer your second question......flat means the ski does not come with bindings.
