Why Brooks? I've tried other saddles that were less comfortable than a B-17 after 500 miles (one of the reasons I tried the B-17). I've tried a saddle that was less comfortable than a B-17 when new, and it never got better. I've never found a saddle that was more comfortable after breaking in that a B-17, and I haven't found the break-in to be that onerous.
