Best weapon against the Pirc?

I am facing the Pirc a lot lately..

Trying to use something like Fischer's setup with the 4 pawns...  and he played an early e5 and also sacrificed a lot to get a piece on f6...

But my opponents are playing e5 themselves, or else hitting me with c5 early and Qa5, and its hard to defend.

Anyone point me in a direction here?

You asked a very hard question but avoid the c5 lines maybe by playing

But then, of course you will have to learn the various follow ups.

White can get a decent game from here.

I was hoping more for castling opposites, and trading the dark-bishops, and then a king attack...  this seems a classic way to attack the Pirc..  Fischer did this brilliantly in some of his games, but that was before a lot of the c5 theory came about...

The line I gave has the possibilities you seem to be looking for.
