On your wood vs DRAM question:
1/ Wood tends to be a little more "ding resistant" than DRAM.
If your board gets an impact ding, the same force will cause a larger ding on the
2/ DRAM is easier to repar.
Matching the grain of the wood, and trying to match the "aged" color of the wood is almost impossible.
DRAM is easy as you just match the color and spray on some paint.
3/ DRAM is significantly less expensive.
Hope this helps,
