just my personal opinion here, but a couple of things that might be worth trying sooner than later, and will probably feel quite alien till you get used to it;
- once you get your straps inboard like a wave board, put the front ones all the way to the front, and the back one almost all the way to the back for a really wide stance (if you need to point right upwind you can pull foot out so that only toes are in the back strap which helps)
- like al said, open your foot straps up so that your straps virtually touch your ankles when you push your feet right in (narrow and tall works for me, so that sides of feet still grip the straps)
- practice sailing in the straps when you are off the plane (even barely moving) as it forces you to position your body weight over the front foot/mast track area, which tends to be where it will be for many of the moves created in the last 10 years
- enjoy it while you can before your bones get brittle (drink lots of milk, or beer?)
+1 for upwind 360's
again, good luck
