I regretted my first B17 Brooks. Tried it on two different bikes, drop bar and flat bar and could never get comfortable on it. It was always too slippery with the smooth leather. It was the hammock effect that I couldn't get use to so I sold it.
Last year I bought my wife and I Bromptons with Brook saddles and she hates her women's version. Finds it uncomfortable and slippery. I am sure it will be coming off this summer. As for me, I am never on that bike for more than 20 minutes so I don't really care what is on it. To me it just looks good.
For my weekend bike I purchased a B67, trying the upright Rivendell style and it was alright but went back to my Specialized Avatar 155 mm.
I have the Avatar on my winter commuter and my everyday commuter. Best saddle I ever had. I want to like the Brooks, they look great and they fit the style of bikes that I ride, I just don't find the ones that I have tried all that great.
On my daily commuter I don't use a Brooks, I use a Specialized Avatar 155 mm wide and it by far the best saddle I have ever used.
