Hello,

How would you differentiate these two boards for learning kids, jibing, low wind and high wind performance?

Thanks

I'm also interested to know how they differenciate.

And I'm interested in the performance of the Go windsurfer in light winds. Does it plne so early as the ultra sonic? I saw the ultrasonic at BOOT it beautifull, but expensive and vulnerable.
I'm looking for a (very) light wind 'do-it-all-board' to practise freestyle tricks (so a strong board is a plus)
