Saddles are always a personal thing based on individual physiology and bike setup. I have drop bars on a commuter, with about a 1" drop. The VO Model 6 saddle ended up being too narrow at 150mm; a Brooks B17 was too wide at 175mm, but the Brooks Professional (alpe d'Huez edition!) is just right at 160mm. There's no way I'd run a B67 on anything where I wasn't pretty much bolt upright with rise from the saddle to the bars and swept back bars... which is exactly none of my bikes right now.

YMMV, but the B67 at 205mm just seems too wide for the application you're describing. I'd go for the standard B17 or the Flyer.
