Greg,
Good luck trimming..... with enough patience, it's an easy task. My very first trim job was a B17 over a year ago and was surprised how well it turned out. Since then, I've trimmed 2 other B17's, 2 B17 Narrows, 3 Professionals, including this one this weekend, a Swift, and just last week, a sprung Conquest Mtb saddle.
I think I'm crazy. I'm currently obsessed with buying and butchering Brooks saddles. I think I need help. I know this thing will wear out in a few months time and I'll be riding stock, unaltered Brooks saddles again....
