I have Globerider kites (GK Lift 8.8 and 17.3) which I dig. Not as fancy design or features as some othert, but the kites rock -- very fast, turn fast and relaunch easily (great for waves), pull hard, jump high.
I bought the new Gaastra GXR 12 ... had to get it replaced under warranty because of a severe rocking/jellyifishing problem. After a bit of mission with local agent, got it replaced. New one did not have the problem, but I still didn't like it. Turns very sluggishly, overpowers badly if you're going fast (you have to stand almost right on the rail and pull as hard as you can to slow it down -- not fun if you're in waves or heading towards another rider). Sold it and bought a Globerider Lift 11.5. I'm now happy again.
GXR pulls like hell -- very grunty, but I recon too much -- it tries to act like a 14 rather than a 12. Prefer a ktie that acts its age
Big floaty jumps, nice construction and features (spinnig leash, etc)
