I can't find it now, but I had a picture of all of the boards laid out. I think it was around 40+ boards. I've built more than that, but if the shape or design element sucks, I scavange the boxes for reuse by cutting the board up
On some of the ultra light weight boards James has snapped them. I'm guessing he's broken 20 or so boards.
I typically do a post-mortem on them to see what caused the failure - again by cutting them up!
So...there are a lot of boards that have found their way to the landfill.
