I have 3 Cabrinha Converts 7, 9 and a 12 and can only say good things about this kite.
It really is hard to fault. I ride a normal 6 foot strapless surfboard and find this kite so easy to use. I have converted the kite to the1;1 none pulley mode which gives a nice bar pressure with quick response. The kite has a good bottom end but not to much and enough de power so that you can throw it around but you also have the grunt when needed.
The de power I would say is in-between the xbow and switch 3 which I find perfect for surfing waves.
The relaunch is instant, like I said this is a kite that is hard to fault.
