How many full BGP feeds would you be handling?  One of the big limitations 
of the Sup2s that drove many people to upgrade to the Sup720/3BXLs was the 
maximum size of the TCAM table in the Sup2.  With a full BGP feed floating 
around 200k routes, this is definitely a concern.  I need to look up the 
table size, but I could see that being a show-stopper for you.

If you opt for the 720, don't forget that you need a Fan Tray 2 and you 
may need to upgrade to the 3000W power supplies if you haven't already. 
That upgrade may require pulling 208V/20A or 30A circuits to feed the 
supplies.
