I skied Line darksides for 2 years (not a true twin) then got Volkyl Karmas last year. HOLY COW... I bought them for our western trips and it ended up being my every day ski. I still pull out the SL and GS skis for fun groomer days.
I believe that twins gained a larger market share of the skis sold last season. I too predict that they will continue gain an increased market share. An untapped market is us old people. I watched other racing parents looking at me enviously as I was skiing backwards away from race fences. It won't surprise me to see them on twins next season.
