Philip -
I used to think the same until I was dismasted in a Category 5
hurricane. In all cases the swages did not fail, the wire parted
varying distances above the swage. Surveyors agreed that the
separation was due to impact (we think other boats hitting the
rigging). The fact that my boat was one of the few still floating
(abet a distance from where I anchored and with other structural
damage) adds credence to the conclusions.
After the damage I changed to Norsemen/repairable connectors
thinking that they could be reused simply by changing the thimble.
That way I could carry replacement wire, thinbles and a few spare
parts as opposed to the swage tools.
Since then, I've not had a rigging failure. I've also managed to
avoid any hurricanes.
