Have you tried the wood pigment, together with a warp{repeat... 
offset... flip<axis>} to make the planks. It can look like:
#include "woods.inc"//to get the ready made pigments and colour_map
#declare Wood1=    texture{pigment{P_WoodGrain5A scale .7 color_map{ 
M_Wood1A }warp {repeat 0.37*x offset y*0.11 flip <0,0,1>}}rotate 90*y 
finish{diffuse 0.85}}
        texture{pigment{P_WoodGrain4B scale .7 color_map{ M_Wood1B }warp 
{repeat 0.37*x offset x*0.05 flip <0,1,0>}}rotate 90*y finish{diffuse 0.87}}

A light toned somewhat redish wood showing planks.
