had some fun on the SB 9'8 at back beach lano and the naish 11'6 at main break lano, both lightish x on days with a reasonable swell running.
The SB was fun, planes ok, turns ok, carrys on down the wave when your windsurfer would have stalled....went through shorey and breakin waves ok, but you wouldn't want to be doing big jumps !!! if i had the spare coin and the room id have one of these for 5 - 15 kts when everyone else is waiting for the wind. good board for kids to learn to windsurf on as well, nice n tuff - bit like the go board.
The Naish is a pig, too big. Nearly got munched several times.just managed to out run the wave by the skin of my teeth.... too much board, sail too far away, even getting rig and board into the water is almost a 2 man job. BUT it's a better board to paddle

might be worth considering the sb 9 if your lightish in the weight department.
