This is not a review but I just saw this product video on the Naish site.
Apparently they developed a new all round B&J board. Normally I don't care much for product videos. I mean have you seen Naish riding in the 80's? He could probably ride a toilet door in waves.
Anyway, have a look at the video at about 0:46. The bottom shape looks interesting. I'd be keen to give this go.
