I now have slightly over 200 miles on my B17 Imperial. I've only used proofhide when the saddle was new and applied 2 coats. I'll probably re-apply every 6 months. At most I'll be putting in 25-30 miles/ride on my Trek 760 with the Brooks. Usually at the 20-25 mile point of my rides I want to stand up and pedal a few strokes to give my butt a rest. With the Brooks B17 I don't feel the soreness at the 20-25 mark. I would say the saddle still causes some discomfort but no pain. I had a few racing type saddles that were painful on longer rides. I'm guessing it'll take another 200-300 miles to get my saddle to the point where it will be discomfort-free, and it may be my saddle of choice if I decide to do a century or an eroica event.
