At our club (Denbigh GC, UK) we changed the steel wire for a type of

I know of a club that also used a polypropylene rope between aircraft
and weak link.
They stopped using that after this rope got entangled within the gear
of an ASK-21, leading to a severe ground loop immediately prior to
lift-off.

The stiffness of the steel wire prevents such an event.
