I have also tested narrower versions of Brooks and I feel best supported by the 170mm B.17. Because each of our anatomies' is relatively unique, I think trial and error is really the best if not most cumbersome measure. It also comes down to your definition of what is comfortable. You may think your Brooks isn't as comfortable as you would like...until you try a more narrow carbon a$$hatchet and are reminded that the Brooks is the most comfortable saddle out there. Lastly...not to disparage the An-Atomica...but I am not a fan of cutting a slot in a Brooks saddle and rebadging it under a different name and claiming it to be an alternative if not better mousetrap. No thanks.
