So if bamboo is about the same hardness as maple, the hit should have a similar feel; good thing.
Bamboo is half the weight of maple and therefore even lighter still than other traditional ferrule materials, so the deflection would be reduced; good thing.
And bamboo is really strong, good thing.
The low deflection school of thought says to reduce the weight in the front few inches of the shaft, hence Predator's drilled out hole. I believe it's 5 inches, but not sure.
How about taking this all one step further and replacing the entire front 5 or so inches with bamboo using a tenon pointing in the opposite direction. Sound feasible? I have no idea how long to make the tenon, the rest is for the engineers and cue makers. I'm just the idea guy.
