I have a Brooks Flyer. It's the B17 plus springs. I am 1000 miles in and it's fairly comfortable for me now but the first couple of hundred miles were not and it probably took 500 miles to compltely break in (others experience immediate comfort with no break in). The springs even though they are stiff make a big difference not just with the bigger bumps but the road buzz as well. At first I was put off by the idea of springs but I actually have come to like the look. My only complaint about the Flyer is it's slippery and I find myself have to push myself back a lot. It's also quite heavy but a small price to pay for comfort.
