I've used the Budwig HQ-2 in a number of antennas, Rx and Tx at QRO and
found they hold up well, even in DXpedition use seaside with the deep
ribs. I use a 4mm "paracord" bow shackle ($8 for 5) from ebay, pin thru
the hole, since it is too small for most ropes. A downside is they
appear to be made of a thermoset plastic so it doesn't take much banging
around to chip a rib. Plenty strong otherwise.
Related, the 6" stock fishing line at the end of a crankIR vertical or
radial would melt when salt accumulated on them and they arced over. So
HQ-2's solved that problem. Screw in electric fence "wood post ring
insulators" rated for 5kv pulses, also arced placed along radials. The
5" long yellow plastic ones have held up on my 160m elevated radials.

The Nylon rope is an insulator until gets wet, collects, decays and collects
more stuff with UV exposure, etc. Assuming your fan dipole is a half-wave
on all bands -- and it should be, keep in mind that RF voltage is maximum at
each end.
I would consider the common dark green Budwig insulators that have a decent
ribbed dirt path. They're stealthy enough.
