Eliminate the blade 9 from the list unless you don't want to spend much money on the kite. From what I have read heard the blade 9 is not as fast or responsive or as good on a bar as other larger foils, it is not as stable either, and also the fact that if it falls in the drink, you're gonna swim. Besides, 9 meters is not that big anymore, i forgot, no depower on the blade either. I have a flysurfer warrior 9.3 and I really like it, I need about 12 knots on a loose AX 160 to start having fun (jumping, rolls, upwind in waves), i weigh 85 kilos. According to flysurfer the warrior is equivalent in power to a mastair one size smaller. I have taken my warrior up to 27 knots on a small board, and I was still in control, although screaming upwind in full depower! My kite would be equivalent to a 7 meter mastair which is no longer in production. The psychos are said to have almost as much power as the mastairs, which would place them higher in power than the warriors. So, I am guessing that the 12.5 psycho would be more powerful than the 16 meter tube kite you mentioned, and would have a much higher top end than the 16 m tube kite. Flysurfer says the new psycho has a 1:4 depower ratio, double any tube kite available. Imagine the possibilites. I can relaunch my warrior very quickly with no hassle, the safety sytem works fine. This has been improved on the psychos. My warrior is truely unluffable(unless the wind drops to 0 or changes direction all of a sudden), it always gently recovers when the lines go slack. The psycho is said to have this stability and improved it as well. The hangtime on the psycho is enormous, every review i have read states this, the lift is very powerful even in lighter conditions. I will recieve a few psychos in few weeks and will post the results and pictures to you guys, we will also have a kitesurf competition in acapulco, so i will be able to compare it directly to other modern inflatos. Anyway, highly reccommended.
THe G-arc, I saw the late protos in action this summer, and they were really amazing, very powerful, very quick to turn, great stability, lift, upwind and construction. My friend traig trumbo LOVES the things, and says it's the best kite made yet. you can see a short clip i took of him in action riding a wave in Malibu, here is the link: http://home.wanadoo.nl/rinke/foils/vide ... c-ride.avi

You may think i am biased, i am the flysurfer dealer for mexico, but these are all direct facts from the flysurfer staff, and from a team rider.
Good luck with whatever you buy and let us know how it works out.
