12.2.25S was the original recommendation from the local Cisco SE when we
built out the MPLS core. We like to keep things *real* simple, so all the
existing interfaces are LDP and would like to keep it that way and not make
any changes.  The equipment is all Cisco 7206VXR, NPE 300 & 400's.  The Agg
routers currently run Enterprise and are very stable so I was trying not to
change it. (Some of the Aggs have 12.2S but I think its overkill.)  Circuits
are a mix of clear T's, frame, frasi, ATM ds3, IMA, FE, etc. 

Is this enough info to base an opinion now for an IOS on the PE's ?

Thanks
