Plethora of UUnet outages and instabilities

My first question is: Have you ever tried putting an RSP2 in a 7505? It 
ships with an RSP, second, have you tried putting an RSP4 in a 7505? It 
works too. Cisco isn't real happy about it, and of course I wouldn't 
recommend it, but it works.

Next, if your network is that busy, you honestly don't keep that 
kind of spare/upgrade equipment around?
