I found some leather thong to make a stronger replacement for the braided laces provided by Brooks. I treated them with Obenauf's to softened them to the point where they can be threaded and knotted, then threaded the laces into the skirts of my Brooks B17 Imperial. Even before using the thong, I didn't have any cutting at all with Campagnolo, Laprade, and Thomson posts, though the laces limit saddle positioning to different degrees. The fore-aft positioning is restricted, even for a Brooks. If you are sensitive to the need for a lot of setback, the Imperial lacing will not help you, with leather or conventional laces.
