while it is true that clay blunts the attacking game the most doesn't mean attacking players can't have success. See kuerten/federer/laver for examples ...
I can't argue with too much conviction against your opinions of Muster and Courier. But, I have seen them play on clay. And both were as brutally intense grinders who have ever played, and would have wins against anyone in history on clay. It's a close call.
