I haven't had a fence up for a couple of years now...mainly because my beans have been a failure for at least the last two years due to drought...but when I do put a fence up, it is three strands. One tape, which I think aids visibility, and two wire. I made a handy dandy device that holds a medium sized spool on the front of my ATV. When winding it back in, one guy drives the ATV and winds the spool as they move slowly forward and the other guy walks ahead and guides/untangles the wire in front of the spool. That goes pretty smooth. I normally take the part of the driver...no sense getting all sweaty.
