Bamboo has been used in cues for years, both for shafts and in butts. It is known as Ramin or Ramen Wood and not called bamboo. Usually found in lower end mass produced cues that sold for peanuts. Laminated it might be useable but without doing that I would hesitate to the extreme to use this substance.
I am not sure technically it is even a wood, it being a mono-cotolydonous [sp] plant rather than a di-cotolydonous one. The difference between a mono-cot and a di-cot being the number of seed leaves produced as well as the distribution of the vascular bundles or veins. Corn is a mono-cot and is closer to bamboo than is maple, a di-cot. I suggest the Wikipedia for a better view of this subject. I is, after all, 38 years since I last studied botany seriously.
