Personally, I think 3050-3055 is the best of all possible eras, provided the Clans are played like the Manei Domini - as GM-controlled ubervillains. Nothing better than taking a bunch of people well familiar with 3025 equipment & tactics, throwing them a few handfuls of DHS, IS LPLs and UAC-5s and then letting them meet some really wierd periphery raiders ...
