By reputation, the
Blanzy-Poure Conti Gilbert #2552 Cementée (got that? - snappy name, eh?) is the one to swoop on. Performance like a Principality, but with Gallic looks - see below. Also the
Blanzy-Conté-Gilbert No. 172F Montgolfier, which might be on the large side for the average holder. Those two recommendations are from Bob Hurford articles, so you can hang your hat on them.
Furthermore, the following are in the fine and flexible class (information from
Kallipos.de, which is well worth a look for further ideas):
