Re: How to go backside
1. often people (and by 'people' I mean a couple of friends I have spoken to!) dont feel comfortable popping up while looking over their left shoulder, because they are right handed. Sounds strange but is true. And I'm natural footed but left handed and I actually prefer looking over my left shoulder and have difficulty popping up frontside...Also, I suspect a lot of people by default turn their board one way (when turning for the wave). I prefer to turn clockwise (to my right) so turn to the backside (remembering I prefer to look over my left shoulder). You may automatically/more comfortably turn to the left (looking over your right shoulder) and then have to re-position yourself to go backside, adding a few seconds and always feeling like you are not quite in the right spot. The 'secret' (if you can call it that) is to practice rotating the proper way - right for backhand, left for front (assuming a natural footer).
2. a slight addition to what DBB said. When going backside you are facing away from the wave but twisting your body to be able to see the wave and you are all off balance. Once up, try moving your feet (particularly the back foot) from 90 deg across the board to more like 45 deg - so instead of your toes pointing sideways they point a little bit ahead. This will move your hips around and open up your body so you can see the wave much easier.
Everyone feels more comfortable frontside because you can see the entire wave and its more natural to lean forward into a wave than it is to lean backwards.
