Hmmm, Thats interesting.Happy It's working good for you. I ran the S wing all of last year. This winter I played around with the flat wing for a few weeks & it seems to carry too much speed into the ball. Put the S Wing back on @7° and it just works. I think the more efficient I'm becoming at the GUT approach to skiing, you know, swing the rope around the pylon faster. Keeping the elbows pinned to my body off the second wake & yawing the ski in the direction of the boat instead of rolling the ski first . You end up having much more speed & time, even waiting on the buoy . It's a little strange seeing the course that way. I feel the S wing is very helpful in getting the ski to shut down just in time to make a nice easy turn which means better angle more speed into the first wake . Repeat until the exit gate.
