hard to say, depends also on what you like.
And the winds you are in.
Basically you want anything that has a good lift and hangtime.
I prefer slow kites, maybe you not. But to land really hard tricks you need a slow kite...
What you would need is a microloop...which only can be aded to older North bars 2009-2012.
Some current bars have stopper balls, ok for basics, but for better tricks a microloop is recommended. Then some tuning and trimming for the bar with kite would be needed if not a North kite.
