So which Kool-Stop brake pad IS the better one for replacing the ones pictured by the OP?
I'm reviving this thread because I also want to replace these EXACT same brake pads, also from a Surly LHT, and this saves me the trouble of taking my own photos.
I've put Salmon pads on all of the bikes that I've worked on and want to do so again but am not sure which to choose from:
Mountain Pads: http://www.koolstop.com/english/mountain_pad.html
Supra2: http://www.koolstop.com/english/supra2.html
Thinline: http://www.koolstop.com/english/thinline.html
or
Phat Padd: http://www.koolstop.com/english/phat_padd.html
