Gary, I have used the bamboo flooring and plyboo (like plywood, but solid, cross laminated bamboo) on a number of projects, but not floors. The info that I got with it said that using some ball test (they drop a steel ball on it, and measure the dent) the hardness is between cherry and oak. From working with it, I will agree. It sands nicely, cuts nicely, but when cross cutting you need to score a line, or put tape over the cut. It has long fiber and tends to have long tearouts if you don't. It takes finish nicely and glues nicely. I like the colors, and the fact that it is sustainable (they can reharvest every 4 years). For any good wood floor, if you want it to last and look good, you have a no shoes house. No dogs as well becuse the claws can do a lot of damage to any floor. As near as I can tell, it is very stable. robo hippy
