Theres like a bazillion species of "oak" out there. Some are really porous and some can have almost none.
Jatoba is crazy heavy. Durable but you'll end up with a heavier camera. Mahogany is a good choice because although it generally looks bland (to me anyway) and mybe not the most durable choice, its very dimensionally stable and easy to work. Whatever wood you choose make sure you buy straight stuff and if you can, quarter sawn stuff. You don'twant your camera warping on you creating light leaks and unwanted movements.
