Some good ideas.  What if I didn't run HSRP on the 2 Internet routers?
Here's the situation.

My client currently has 1 router with 2 WIC's with a T-1 FR to each.
BGP is running but uses the second circuit purely as a backup.  The
client wants to load balance on these two circuits.  Ideally, he would
like to move the 2nd circuit to a 2nd router and load balance that
way...

Maybe there are some simple BGP changes??

I tried to set this up also. You would be able to work around this
somewhat
if the PIX could identify both routers HSRP MAC's based on a default
of the outside interface itself, in theroy arp'ing for the higher
priority. But the PIX can't do that either.
