That makes sense. But wouldn't that same potential weakness also apply 
to a wire either directly soldered to the PCB pad, or to a PCB pin?. 
I've had that happen on some perfboard prototype builds using stranded 
wire that got some rough handling. (the soldered joints to PCB pins 
weren't reinforced by heatshrink or hellerman sleeves or anything, so I 
wasn't too surprised...)

This is an interesting thread, thanks for everyone's input.

cheers,
