We had a sonic and waroo back to back a few days ago.
The waroo is not a direct copy. Have a good look at the canopy shape
and profile and you will see why. Also ride both and feel the difference.

I am not going to post my review on this kite as I represent Best
in Brisbane and the forum and shop trolls will just post some stupid comment. Come and fly the demo for yourself and see why the first shipment is nearly sold out!

I started kiteriding more than 4 years ago in Adelaide and I've spent a lot of hours on water. First on Cabrinah Black Tip 12. Later I had Airush Lift 12, Naish X2 16, Naish X3 12, Naish V4, and Naish Raven2 16m. The heigh aspect performance kites (fast and very heigh jumping) and I love them.
Few months ago I tried Cabrinah Crossbow 12. There was a strong gusty wind and everyone was riding on 7 or 9 m. The kite was very easy to control and stable. But after 10m of riding and 7 jumps I had had enough. Too heavy bar pressure and very slow on jumps (you drop like a rock when you are too heigh) And ... too expensive.
So I decided to wait for the competition to release their bow kites.
Last Saturday in Brisbane I had a chance to test SOnic 11 and Waroo 9.
It was gusty around 15 and 23 knots
Both kites are great. And they are completly different. The idiots saying that they are the same have no idea what they are talking about (Warro is in Australia only second week so they haven't seen it yet) It is like saying that Mercedes and BMW are the same cars because they are German and sedans.
I spent 2 hours riding them and I am realy impressed. Very powerful, easy to control in gusts and on waves, heigh jumping and fast kites.
I order 9 m Waroo - better and easier bar and $1250. But my advice is:
don't buy Crossbow or Swichblades, go Sonic or Warro and try before you buy.
