The problem with shorts is that bubbles can expand well beyond rationality. Cash or bonds is what I am doing.

That's not a problem at all, you just roll some of your bull market gains into close dated ATM puts periodically. If the market is sideways sell calls.

Genuinely curious, why do you need close dated ATM puts. If all you care about is protecting upside can't you just put in limit orders.
