yeah i skied on them for about a week when i was coaching at the ontario k2 championships.
They have the same delam problem as this years k9.1 as the tips on the k11 just seem to explode! Nothing a little duct tape and rivets can't fix though.
Other than that, they are a realllly sweet ski with lots of sweet spot and snap. They have a super stiff tail which is good for anyone who powers through from the back of the ski.
Overall they are a good ski, but if you want the best slalom ski around get the fischer rc4 slalom. It's the best ski i've ever used.
