Is it possible to be agnostic on Brooks saddles? I had a B17 for about 5years, before it turned banana shaped and I had to drill holes in the bottom and tighten it up with shoelaces.
I found it was very comfortable as long as was doing alot of miles on it. If I switched to another saddle, then went back to the B17 after a few weeks, it gave me arse ache and also some knee issues. Regarding the knee issues, I think it's an ergonomic thing, as it's quite wide - feels like sitting on a dinner plate at first - and maybe it splays your legs out slightly. Just a guess. One tour I started without spending any time on the B17 beforehand, it took 2 weeks for the arse ache to stop - but it did and then it was a non factor.
I think your arse reshapes to the Brooks as much it does to yours. I liked mine, but couldn't be bothered with the faff of adjusting to different saddles, so just put Charge Spoons on everything.
