I have tried Bamboo, Maple, Hickory, Ash, Elm and a couple more as backings. I would have to say that it would depend on what the core is when I choose a backing, I never use a hardwood on a dense tropical. For performance I wouldn't be able to positively say that Bamboo performs better because i think it has more to do with choosing the right backing for the core. I have come to not trust Hickory as a backing, possibly because I can't cut my own. Maple on the right core and the right design will give top performance and I've yet to have a Maple backing fail on me, I am quite picky as to which tree I cut for backing material.
