I have a B-66 (close cousin to the B-67) on my Superbe. As noted, it's designed for an upright riding position, and for that it works very well. If you have dropped handlebars you probably want something different. I use Brooks Professional saddles for those bikes and have no complaints. As noted above, the Brooks Flyer looks to be a B-17 with springs, but I've never tried it and so can't comment beyond that.
