Ok been practicing and couple of things help.
1) you hear alot of peole saying trow your head and look where you want to go. I was throwing my head looking over my shoulder which was pulling me off balance. I've found it much easier to look under your armpit as you rotate. This gives you the momentum from throwing your head into it but keeps your weight centred and more easy to balance.
2) lock your core when you pull your shoulders so they are width ways across the board.
3) don't rudder with your foot in the air. Keep it quiet and let the shoulders go the work
Just a few things that helped me out today
