Very creative, Rob. Potentially messy, but creative, no less.

Only problem with your test is that for natural stone you're only allowed a maximum of a quarter-inch deflection in the center of that floor. And you gotta have a couple friends help you do the jumpin'. Well, unless you got you some really big friends.

My opinion; worth price charged.
