And I only ever use it on bikes belonging to people who just must have a shifter that puts an a sharp bend in the cable.....out of sight, out of mind.
Agreed. Although cables do fray at the rear mech pinch bolt this is normally fairly obvious in a way in which shifter fraying isn't.
BTW I consider the design of the pinch bolt on many Shimano mechs to be prone to causing fatigue because the cable wraps round an excessively tight radius. Mind you, if you are running STIs they seem to fray in there about the same time so maybe there isn't that much room for improvement....
