This is one of my favourite high speed turns especially on flat water. For me it all came together with the kite. Come into the turn edging hard heel side with your kite low. Then crank the kite to make it go the opposite direction - as you feel the pull, crank the turn onto your toeside. If you have enough speed you can ride away toeside, if not switch 180 back to heelside.

yeah seems to be my problem. I have the kite to high. I tried having the kite lower it this morning and i got the turn alright just need to work on riding toeside. Thanks heaps guys.

The same as ^^ but

Try a downloop transition (on youtube).
Basically, just keep the kite around 11. Steer it hard towards the ground and keep turning so that it loops around. With your body, follow the power of the kite by steering down wind and then regain your edge. Suddenly you find yourself toeside!!

wassaby, it's easier on directional than a twin tip. It is one of the few times when watching the kite makes the move easier as it allows you to follow it round. Leaning back a bit also helps.
