I can only praise the Ozone Alpha V3 Ultra X kites, allegedly the lightest on the market, and they certainly feel like it. Performance is amazing in the surf/surfboard, next level drifting and very sharp turning. I have an 8m and a 16M, the 16m is fantastic in lighter winds, works much better for me than any other large kite I've tried.
If you are around Lennox or Sydney we have demo's?
