to frostyballs: yep join the 'walk of shame' club mate haha. I'm confident having my left foot forward and actually can go upwind quite well and in control. My right foot forward on the other hand is still pretty rusty! we'll all get there eventually! It sounds like you'll be a fast learner.
to Grillsy: mate I've been in the same boat. had to do a self rescue once because my kite inverted. That didn;t go too well and a guy came and helped me out.
straight after this I practiced my self rescue several times.
before you know it a few sessions later my kite inverted again. This time however, because I practiced, I squared away my self rescue easily. I grabbed my kite and sailed in without any issues.
This really boosted my confidence. Knowing that you can easily come back in shore when things go wrong is a great feeling.
So morale of the story: I don't know if you have, but I would recommend practicing your self rescue over and over. It will boost your confidence!
