I don't think it was the Nigel Smythe bags that were the point of controversy, it was the older Rivendell Baggins bags that they don't sell anymore.

SadieKate, thank you for reminding me of the Berthoud bags. I really need a small seat bag for my new single speed, and the bike is too pretty for a regular wedge bag, but I don't want something huge. There are a couple of Berthoud options that would look great.
