Looking for a bit of advice seeing as this will be my first specific set of kites,

I've narrowed down my new kite choice to Airush Wave or Ozone Reo.

People tell me that they are both great kites for waves, but dependent on the waves. What would be the suggestion between these two options for Onshore / Cross Onshore? I like a little bit of unhooked poppy tricks on the twin-tips every so often too.

Generally I've heard that the Airush are generally faster more fiddly kites, whereas the Ozones are more drifty down the line kites?

Lastly, recommendations for sizes? My last quiver was a 2011 11m C4 and a 9m 2010 Catalyst using primarily twintips, I'm 84kg, and planning on using these new ones mostly on a 5'10 directional.
