Caveat: I have never toured. But, I am training for it by riding back-to-back 60-70 miles a day for four days straight. A couple days off to attend to the mundane things of life and back at it. I figure that qualifies for the purposes of your inquiry.
My answer to your question is: No, I can't. Not trying to be trite at all. It's just that when I got my Brooks, I quit looking elsewhere. Maintenance is an over rated issue although I waterproof mine as soon as I get 'em un-packed. I have three now.
