My impression of your comments leaves me thinking that you want to find a "golden" pace-line or group that will get you through a 100 miles with the least possible strain. (good luck with that) My experience would suggest that you need one or two really strong riders that would concede to your ride abilities and wishes and give you the chance to work or sit up on your behalf as the ride unfolds. Otherwise you may get with a group that will hot-dog flats or ride grades unevenly.
You may be able to get another five hour century but - it is doubtful you will ever see your best result without a strong rider (or riders) thoughtfully pacing you.

Well, if you're talking about 5 hour centuries in group rides, it's not that hard if there is (a) relatively flat terrain in your area (OP lives in Maryland, so...check) and (b) well-organized groups that know how to ride a steady double pace line. I've done plenty of 5 hour centuries with strong groups. A group of ~20 disciplined and modestly strong riders and it's a piece of cake. Some may take more time on the front, others may not take any, but the group moves along at a steady clip. No surges, no yo-yo-ing.
