Well good luck. I'm riding a Fizik racing saddle (touring bike) which is fairly comfy up to about 50 miles so I bought a B17 Select which has the weird problem of the skirt and/or nose rubbing on my right thigh. Saddle appears symmetrical (maybe my legs aren't?) but I never had the problem with numerous cheap or nice plastic saddles. Long time ago I bought a Brooks Pro from a shop who failed to mention that it was used. Had an uncomfortable sway & couldn't fit the Campy wrench onto the tension nut w/o fear of damaging the nose part.
Many swear by their Brooks (the hardness never bothered me) but getting a nice fit seems to be more hit or miss vs plastic saddles which usually have more of a triangular shape vs Brooks' T-shape. So both Brooks I've owned were uncomfortable even on short rides (not a break-in issue) but I've never had a plastic saddle that uncomfortable.
