What's the BEST way to play a ratings downgrade if it happens?

I'm not talking the obvious short the market.

There's got to be better ways.

I had the similar question in 2007 about what to do about a possible housing bust. It was only til things were totally crashing did I find out better ways I could have positioned myself for that event.

So, what are good ways to position oneself to maximize potential profits if a ratings downgrade of the USA occurs?

 

Move to Canada

 

anyone with good ideas?

 

Buy t-bills... Or do the spread: sell munis, buy t-bills. Have to be careful with it, though.
