One thing for sure is Brooks saddles seem to change a little over time. Like weather. If it is bad now, 300 miles later might be back to perfect comfort again in my experience. Then back to worse, then back to better. Like for many miles it is perfect, then changes and now perenium pressure, then later fine, then rivet, then fine again for 1k miles, etc. Proofhiding and a 1/8-1/2 saddle nose nut turn can help.Sometimes changes adter riding in rain. But stull tge most confy saddles ever up to 130 mile centuries fir me.
Back to my daughter. Went through a gambit of saddles trying to solve her drop-bar road bike dilemma (also saddle height and bar height equal).
Rivet Indy loaner, Specialized. Finally succeeded with Fabric Radius - she adores this saddle.
