Back to basics:
1. Edge through the wake (you speed up then stall and flatten your board befor you hit the wake, stay on edge all the way through the wake)
2. Keep that rope in tight to your hip
3. Stay tall off the wake and look at the boat and not where you are going.
Those are the basics I saw. It is hard off an IO because you have to travel so far to get wake to wake. The urge is to try and get as much speed as possible to actually make it all the way across. Try slowing things down and doing 1 wake tricks and go for height. It will help you get the basics down and when you go for wake 2 wake stuff you will have the height and technique to rip it up. You might try short ropN it from time to time and work on height and you basics, shorter rope makes it easier to get wake to wake and you only have to cut out a short distance to get what you want out of the wake. Hope that helps
