The pansh fabric coating is quite good it doesn't really get wet much like the lotus, so because the kite stays light it will relaunch in quite little wind. The drainage however on the pansh is not as good as flysurfer, so even a little water starts to become a hassle. The split cells are one of the problems as each cell has a little hole to drain and it takes time for water to move cell to cell, doubling the cells really slows it down. The other problem is pansh doesn't have a continual drain(open hole) in the tips unlike flysurfer, so water takes longer to exit and the velcro seems less likely to open for some reason. The tip could be altered but there is benefit to air pressure by not doing it the flysurfer way.
Turning is not quite up to latest flysurfer standards. Turning is something I think flysurfer puts a lot of effort into, maybe because foils have been highly criticized for slow turning. There is negatives to tuning a kite for better turning, a loss of power and stability. Good turning kites tend to over emphasize the tips, they become unstable while the middle of the wing goes unused. Using a pulley bar you will get turning faster than a flysurfer anyway. I think turning is over rated, I surf with kites and most guys use the fastest turning kites available and are perplexed how I can ride slow turning kites and often not even turn them. But to me this is the most enjoyable way to ride waves with a kite, over the years I see more and more people ride like this so I "may" be right
C does seem to help with responsiveness. I remember Funalex talking about C and turning. But again you loose performance tuning for turning. Do you want best lowend or turning? I don't think you can have both
Mind you increasing the camber on my A15 certainly helped both.
Foils in general can be messy when flagging. Surprisingly or not the fifth is the cleaner option with the best chance for relaunch. The most important factor for either fifth or front line flagging for relaunch is to have a stopper set at the correct point. Where "exactly" that is I couldn't tell you but it is somewhere just after the bridles are slacked, maybe within 1-2m. Too much slack and you start to get tangles , too tight and you start to lose some flagging, especially if you get tangles when/before flagging! I played with lengths a bit but I really only flag to kill a kite, so it hasn't interested me more than to know that and so also I don't even use a stopper.
