agree with jb...diff stokes for diff folks..a good kite for waves is determined by your style first...
stability is realy important, when riding slight cross offshore its makes wave riding so much more fun (and easy) but gusty directional wind can make a timid kite the session from hell.
what i like about my kite the most is its ability to have slack lines and instead of hidenburg it just floats back into the window until the lines tension.
my wave riding is fast and powered..that's where a kite with power in the turns does well and also very easy to turn to get that power is important for me.. depower isn't as high on my list as turning power. but then getting ripped down the line isnt a good thing either when in overpowered conditions, but thats more about using the depower strap not bar throw anyhow - otherwise its a poostance down the line

. other thing i like about power in turns is that it gets me away from crap situations faster than a kite thats power is from park and ride.
a well made kite won't determine if it will survive a wave...its almost all down to luck realy... how fast you can relaunch would be a bigger preference in regards to crashing anyhow.
