My Caylors are the same way and I still ride them regularly.
As far as bamboo splitting easier I have noticed this can be the case. I am no expert on woods but I have done several projects this past year, one of which was recycling some laminate bamboo flooring and building a monitor stand. Bamboo seems very fibrous, this is probably because it is a fast growing grass and not truly a wood. I wonder, do they press flat to make into a "wood product"?
Anyway, I noticed that the bamboo is very easy to split or fracture along the grain. It was different than splitting say a piece of cedar because the split stopped and didn't want to continue all the way through the wood, like ripping into rip stop nylon or something. I also noticed that the bamboo fibers would start flaking off a little and would be sharp and hard. Its an interesting material to work with.
You have probably worked with way more bamboo than I have, have you noticed any of the things I mentioned? It could just be the manufacturer of the laminate flooring I was using.
