GSR Engine 2 GE cards have serious limitations around 
ACLs and inbound filtering. The Engine 5 card is far superior.

(if you want need to mark inbound traffic into a specific CoS
setup at a peering point for example - you are in trouble).

I'd suggest that you look at that for when you start to push
over 250M on specific interfaces, most notably around the edges 
of your network.
