My two drop-bar bikes have/had B67 saddles. (bars lower than saddle)
My moustache bar bike has a B67 saddle. (bar about even with saddle, slightly below)
My upright bar bike has a B68 saddle (bar about even with saddle, slightly above)
Not sure what your BF means about width getting in your way as you bend forward. The width is behind you as you bend forward. Can you sit on a bench and bend forward? Is the bench wider than a bike saddle? Does the width get in the way?
Wider saddles are more necessary as you sit up taller, because the angle of the pubic rami/ischial tuberosity "rockers" widens as they go posterior from the pubic symphysis. A person might comfortably ride a fairly narrow saddle on a racing bike, but not be so happy with that same saddle on a cruiser. Same bones, just weightbearing farther back as the pelvis goes from an anterior to a neutral tilt and the contact shifts from the narrower portion of the "rockers" to the wider portion.
But that doesn't mean a wider saddle cannot be used on a drop bar bike, no more than sitting on a bench means you cannot bend forward and touch the floor because the bench too wide.
All this is academic, however, until you get your sit bone measurements!
