Before going forward, I would make sure your ISP, if using uRPF, is using
loose instead of strict, or even suggest they just an ACL instead.

Since you're just using dual default routes, there isn't any point in you
running uRPF on your upstream serial interfaces, just on your ethernet
interface (and any other downstream ints). So disable it entirely on your
serial interfaces.

That's about all there is to say about it...should work fine when
configured correctly.
