Raw Wood Grain Shaders. They don't play too nice with TGs ability to render small detail, but it looks decent I guess.
You can play around with the base wood grain PFs (for diff color definitions or what not), but keep in mind you'll likely need to rebalance the low and high specular/displacement colour adjusts to get a smooth displacement/specular map. Note that you'll also have to orient to wood grain direction as well with the Grain Orientation (Rotate) shader.
Realized I packed up the wrong save with a little too much surface displacement. B has less surface displacement to show grains better.
