Ancient history but…
Years ago most of our collegiate team went to a 3ev class C. I was the only slalom only skier and got a Sanger for second round. Non of us had ever skied behind one. As Horton said the wakes are HARD. It was a 3 round, but only single eventers got to to ski rd 2.
Everyone was to get the Sanger for 3rd rd the next day. Flash forward to 8am Sunday morning after a brief lake side devotional by the host club. I said to my buddy “watch this” as our first girls skiers headed for the gates at -15/34. The F bomb reverberated across the water as her knees got jammed up to about naval level! (I did mention in passing the wakes we’re a little firm?)
Totally unrelated but in Montana at the moment and saw two Sangers on the Gateway to the mountains lake. Didn’t even know they were still around.
