I like that 'blanket' analogy.
After my Pa contacted Terra Firma at well over 100 Kts at 30 degrees in his Carbon fibre glider fuse, the nose did indeed resemble a blanket if you poked it, but it held it's shape - almost eerily. But, he survived it, although he was also quite badly broken. There is no possible way that any non CF machine would have protected him to that extent. It was the "bit by bit" disintegration that saved him.
So, crash-wise, I think I'd prefer my chances in the Carbon composite.
Having said that, I'd only want to crash in a newish one. The inspection problems and the way that CRP reacts to electricity, fire, freezing, de-icer etc.. does worry me.
