Thanks.....Yeah, I think I might try that if I really need to do something
about that outbound LB.  At the moment, it's the inbound (download) traffic
of course that is the heaviest and that LB is based on the upstream device,
my asr9k, which is performing LB fine across those 2 gige's

Thanks again folks

LACP isn't supported on the 7200 (tried in IOS 15S). So I wouldn't recommend
attempting LAG's on the 7200.

As suggested, run IP on two links and have the same IGP metric for load
balancing + BFD for early link failure signaling.
