While I'm waiting for my bike to be delivered, I'm trying to decide which Brooks to get - either the B17, the B17 Champion Special, or the Champion Flyer. I'll be riding over smooth and rough pavement, and sometimes dirt trails. The main negative point about the Flyer, according to Bill from Wallingford is the difficulty mounting saddlebags. Is the Champion Special much more difficult to break in than the regular B17? Will I truly notice any difference with the Flyer? I'll probably be "going light" over most bumps, anyway. What do y'all think?
