Funny...I was going to ask if your traffic was mostly VOIP or 
something...because the PPS rate seemed awfully high for the bit rate.

You mentioned full routes on Sup1's.  I didn't think that was possible. 
If your planned upgrade is just to Sup2's, you might have a look at

The prefix-list is somewhat outdated now, but the beauty of its design is 
that which it doesn't know about, it permits down to /24, so all you lose 
is some route filtering.

Contrary to what Roland may think, the 6500 is a popular box for data 
centers / ISPs doing all ethernet.  It may be lacking in things like uRPF 
and netflow, but for line-rate capability packet forwarding and the 
ability to shrug off DDoS's aimed across it, it's kind of the sweet spot 
in price/performance.
