Fran, I don't know that 'durability' has got a lot to do with it. Come on now, we all know that donny's winds of change will be more influenced by some internal feature or other.
I'm going with Diki's 8-week secenario.
I'm not sure now whether or not donny is more famous for his musical abilities or his gear instabilities.

It's all rather entertaiing, though - and the man is an entertainer. Right, donny?
