When I wrote that I was thinking of multiple paths, rather than
asymmetric paths. Compare the TCP performance of packet-based
load balancing to session-based load-balancing.

Nor would I. It might make sense in a flat topology, but ours is
more hierarchical. I find network management easier when we push
the details of tail-circuit connections out to the access
router. The less complications in hub and core routers, the
better.

In core (EGP) routing, absolutely. However, I haven't noticed
any ill effects of flapping in our internal network.
