My son played a lot of baseball in wood bat leagues and tournaments. He preference was bamboo, any brand. Check one out and see how your son likes it. They seemed to last longer as well.
My son had a Brett Bros bamboo for the cage, and a Bamboobat before that. Both looked, felt and sounded great. (the finish on the Bamboobat is like fine piece of furniture) Both lasted a long time. But I wouldn't recommend either for games. From what I've seen and felt I don't think they have the same pop as good, solid wood bat.
I've never heard of a difference in performance between wood and bamboo. I'll have to check that out for myself. I don't recall my son ever noticing a change in the pop.
