A very nice ski. I have put around 30,000 feet of touring on them and a little lift assisted touring.
Me: 6'0" 160lbs type III +/-
Skis: 169 X Response with speed radical binding and dynafit tlt6 boot
Conditions from great to good to bad: ice, crust, wind blown, powder, corn to slush. My typical ski is a 170+ but for this ski I got a 169. I was a little concerned I'd gone too short but they ski'd well for being a smaller ski, toured nicely and handled the conditions well.
