Hi mate, I have a 10x29 and love it, it will catch the smallest bump and only gets better the larger the waves are. I also have a Maddog 9x32 to compare, the Nalu really likes the water to be calm. Bumps and wind that the wider Maddog brushes of will have you on your toes waiting out the back. It's not bad just noticeable between the two. As for riding waves it's fast, the narrow tail has it turning easily and it a really fun board to surf. I like it as a quad, whereas I prefer the Maddog as a thruster.I weigh around 95 kg and find three to four hours surfs not problem.
If surfing is the main game it's a great choice.

Maddog tail on the left Nalu on the right, gives you a idea how it surfs so well for a long board.
