We have some 7010s running as backbone routers, mainly for regional peering
purposes. The 7010 is identical to 7000 in performance, just less slots.

No problem. Problems seem to occur more on the 7000s since they normally have
more cards and trunks attached and hence more likely to get loaded.

Just make sure you do not provide transit between two networks. Since they
are your providers, the traffic may kill your links if they've got
problems between their peerings/transits.
