Demo'd a number of skis in the past couple weeks, but settled on the K2 Crossfire. The bindings (factory Marker 12.0, NOT the Marker 12.0 Pistons) were thrown in for $50, which got me out the door. But I'm looking to switch them out. See pix below. Would a Marker Piston binding, such as the Marker 12.0 Piston or Turbo be better ... or not enough of a difference to merit the extra $200.
