On stranded cable, it often happens that some wire will swap when you
insert the connector. Remember that to work at gigabit, you need the
four twisted pairs to be properly set: more risks to make a mistake...

I know I prefer to buy my patch cords (stranded cables) ready made,
while I can do the wall wiring (solid cable) by myself.
