Tassos, Basically, if you have a Sup720-3B, it means you have a PFC3B. If you have a module with DFC-3BXL then you will gain nothing, as the DFC has to match with the PFC model, so basically even though you have DFC-3BXL, it would operate in 3B mode.
The same works the other way. If you have Sup720-3BXL and DFC-3B on some module, you would basically force the whole router to work in 3B mode. The reason for this is very simple. The DFC is basically a distributed replica of the central PFC, so they can only operate in the same mode.

I have both 6500/SUP720 and 7600/RSP720 systems and i would prefer to get DFC-3CXL cards (instead of DFC-3BXL), so i can use them at their maximum efficiency in both systems (interchangeably). Isn't that possible?
