I just finished a week-long bike tour (GOBA) of moderate distance (320 miles) and lots of climbing (for me anyhow, a flatlander) w/the Imperial.

The saddle developed a squeak, so the mechanic at Century Cycles (shout out to Derek, you are awesome!) lubed it up w/beeswax (no proofide handy) and tightened the laces, which had become baggy. No more squeak.

The saddle felt significantly firmer after the ties were tightened.

Adding ties might be just the ticket for your B68, Thorn. Especially considering the width of the saddle.

As to weight, I'm "a hundred and plenty" and so, far NO issues with the sagging or pinching.

I am so impressed w/this Brooks Imperial. I ALWAYS had chronic sore spots and issues w/the Terry Butterfly, I just thought I would have to suffer w/it to keep riding.

The Imperial is so comfortable w/absolutely no chafing or hot spots.
