The "Aged" version of the Brooks B68 is better,....BUT only after I tweeked mine as I don't care what Brooks ads say about ANY of them being comfortable from day one,...they were still hard. (initially! :-)
But after I did my usual "treatment" I do on ALL my saddles, ....it's comfy and the wider B68 is fine on my behind! :-)
I Do like the "Aged" version because the pebbled surface soaks in the first application of the Brooks "Proofhide" product better than the smooth grained saddles. I know Brooks used to say Aged Saddles didn't need Proofide, but that's BS in my experience! I do both Top and Bottom,....and THEN the real workout begins. I mount the saddle on a bike, and fold a few layers of canvas over the top. I use a couple of the US Mint coin bags I have laying around,...but some old jeans or similar should work as well....
....then I use a 2-1/2 pound leather mallet and hammer into the saddle top about 300 times, covering as evenly as you can. I do the first hundred strikes a bit more moderately, and the last 200 with stronger hits. The early strikes begin to loosen the fibers and later ones add greatly to the Comfort level. Now the saddles feel like a well "broken in" Keister Cushion!
I've "treated" maybe 10 or 12 Brooks leather saddles this way over about 25 years, and NEVER had one tear,...or even scratch from the leather mallet strikes,...AS LONG AS you use several layers of canvas or similar to protect from direct contact with the leather mallet. (I seem to recall using a rubber mallet once too a long time ago?)
I also know that Brooks or any other saddle maker would likely say you are "abusing" their product, but as I bought it I can do what I want to to it. My experience is it does NO harm, and only improves the riding comfort for Immediate results.
Now nearing age 64, I don't have TIME to wait a few years for a new HARD and uncomfortable Leather Saddle to "Break In",....and when I was younger I didn't have the Patience! :-)
Oh,...i'll say it but it should be obvious,...DON'T use a regular STEEL Hammer to do this! It doesn't spread out the striking forces enough, and concentrates the energy in a way that you may create dimples or other damage to the leather. In the end you assume any risk, but my experience over decades has shown this to be a safe procedure if done in the way I outline.
