Shortline is your max speed at -22 and beyond. In the entire world of people who water-ski there is really only a small percentage who can even run a slalom course. Even smaller -22 and beyond. I agree with mwetskier's post, lets not make this any more elite than it is. Anyone who skis with me, if you are -22 and shorter, you are shortline. If you are -38 and beyond, I am just pissed cuz your better than me......damn you....OF
