"Kahi" posted a comment to my Boiled Linseed Oil post, and included a link to the following video, which apparently shows him surfing a pine alaia. Here is the description from the YouTube page:
Roscoe shaped me this alaia, been riding it for about a month and am completely hooked. When the surf is smaller all I ride is this thing. Its made of pine, 5'8", 1" thick, tapered rails, and a single concave. It used to be a 6'6" but we cut about a foot off of it so it would fit in my board bag. Glad to say it still works. Jeffreys Bay is unreal, this place is awesome. Thanks to Louise and Rich Hambloch for filming.
Here is the video:
