Thanks for the great explanation Mike, now do you have time for one more question?

I was looking through all of your pictures, saw the foam 4x8 sheets prior to being ripped, couldn't you have used them much like Kurt uses the 3mm ply, that is, rather than cut them apart into small strips, then glue them back together, how about cut them into much wider strips, to save time and effort? It looked like the foam was more flexible than ply would be, so couldn't it be -bent- around some of those corners without having to rip it into small strips? Or is it much stiffer than it looks?
