Ya know something else.... Sometimes you'll run across Natural color bamboo flooring that is junk too.
Years ago lumber liquidators sold some cheap bamboo that i wouldn't put on floors, much less in my bows. The stuff was just limp compared to Moso bamboo that was Carbonized. And the stuff delaminated easily..
The process they use to carbonize the stuff is like a heat treating process. i won't buy the natural bamboo any more.
Max is right... just stick with Rock hard maple and you are bullet proof. I buy the stuff at a hardwood company 2" X 8" X 10' lengths, and select my own vertical grain boards. Its become a staple for bow lams for me.
