imho, yes.
My first brooks was an older used saddle, well used. I adjusted it, it was fine from the very first day. This was before i even knew you had to break them in.
As different people ride our tandem, we leave the B67 on it. It's getting more broken in, and it's getting better and better! The last person to put 500 miles on it rode it with the nose pointed WAY UP, and it doesn't seem to have affected it adversely for me.
