Consider a
BROOKS "Narrow"
B17 saddle ...
By my reckoning, MANY people who have had trouble with the saddle did NOT have it properly adjusted ...
... Meaning that you have to lower the seatpost by several millimeters because the distance between the rails and the top of the saddle is greater on a Brooks-and-some-other-leather saddle(s) than on a plastic saddle.
So, if you opt for ANY saddle other than the one you are using, then you should measure the distance from a point on the frame (I use the middle of the BB spindle even though it is the hypoteneuse of a virtual triangle to the to of a known saddle height. I also measure the portion of the saddle which I sit on to the rear of the brake's "horns" to ensure that my forward reach is essentially the SAME regardless of the width-and-height of the handlebars.
That's (also) an indirect way of saying that your current saddle may be a fraction of an inch too high and/or you may be straddling it (which seems to be the fashion in the past few decades!) rather than sitting on it.
The "narrow" variant of the Brooks B17 is wider than most
plastic saddles ...
The "standard" variant of the BROOKS B17 is really wide ... but, choosing-or-not-choosing the wider variant may be more of a cosmetic issue ...
The width of the BROOKS "Professional" saddle is in between the BROOKS B17 "narrow" & "standard" saddle widths.
That is, while a saddle CAN BE too narrow, it is almost impossible for it to be too wide.
WHAT saddle are you currently using?
BTW. Beyond setting the HEIGHT of a Brooks saddle at the proper height, the only other (
but, significant)
caveat is that leather saddles need SOME regular maintenance ...
I am NOT a fan of Proofide ... maybe, I don't know any better ...
I prefer to remove the thin, shiny surface with some very fine wet-dry sandpaper ('0000' steel wool is an alternate) and the treat the leather with SNOSEAL.
Plastic saddles which ARE comfortable are of an earlier vintage when they were in direct competition with leather saddles ...
