I'm not a course skier (no acess to one) but you do hear skiers complain about cheaper ropes being too stretchy. I normally buy/use 8 or 10 section ropes from Straight Line and other high end manufacturers. I figured the goal was to have as little stretch as possible.
There is a subtle balance in ski ropes. You want to stretch your ski ropes before using them or you can do it by just skiing for a while. The balance is a little give, but not a stretchy rope. Most skiers perfer the high strand count ropes from SL or Masterline.
