I have a little over 5,000 miles on my standard Brooks B17, yet I'm still not pleased with it. I feel like the edges flare out too much when I apply my 170 pounds to it. The result is a feeling like a knife rubbing against my thigh on back to back rides of 50 - 60 mile days. Has anyone tried to modify their standard B17 with holes similar to the Imperial , then using a leather cord to keep the edges of the saddle from flaring outward ? If so, how did you make the holes, with a drill, or a punch. Was there any improvement ?
