I just learned switch toeside and found that the easiest way to learn for me was to shorten the rope all the way to 55'. I learned on an old school SAN. At 55' you can just charge the wake as hard as you can until you get the form and muscle memory down.
This weekend I just got my Switch TS Backroll down...
Everyone makes fun of the short line stuff, but it's so easy to learn stuff its silly! I learned how land blind, raley, s-bend, and scarecrow all at 55' and 21 mph. Of course now I do them at 75'.
