There is a review on http://www.kitesurf.co.za
From all the sources I have heard from the new black tip is really impressive, and better than the Rhino 2.
Unfortunately they have tested the new bar, as only some demo kites arrived in South Africa but so far the kite is definitely up with the best.
I know Andoni rated some of the new kites as follows:
1. 2003 Black Tip/X2
2. Rhino 2
3. 2003 CO2/Aero 2
