[c-nsp] Stable NPE-G2 IOS for SP?

[TCIS List Acct]

We've decided to go with multiple 7206VXR/NPE-G2's for our edge routing 
(replacing older NPE-300/400 devices).  We have simple needs -- BGP, OSPF, 
NetFlow, and some small ACLs on the WAN interfaces.  Since the IOS selection for 
the G2 is somewhat limited, if others can share what IOS release has been stable 
for them, it would be appreciated.

TIA.
