You definitely need some way, no matter how sophisticated or primitive, to hang vertical (or nearly so) coarse drops that the bines can successfully climb. Unlike
vines, these bines have no significant tendrils, relying entirely on an almost velcro-like array of tiny hook-like spines to hold on to anything.
So using stuff like wire or monofilaments usually are non-starters for drops. What you want is on the other end of the coarseness scale. Sisal twine (aka bailing twine) and coir (<= what use) are two of the best.
You can hang drops from pretty much any suspension line material that can carry the prospective load. If you allow up to 20 pounds worst-case per mature crown and factor that in to suspension line rating, then you just need to assure that the end points of a suspension line will stay put.
fwiw, I use 5/16" multistrand nylon for my suspension lines as it's durable, wicked cheap, and can carry the up to ~200 pounds 11 harvest-ready crowns might impose (one side - the other side has my other four crowns, though I use the same type line). The ends pass through eyebolts at the top of 10' 2x4 risers I erect during hop growing season on top of my 2nd story deck, then are tied off to cleats mounted on the risers around elbow height.
There's enough slack in the suspension lines to let me untie from the cleats and lower it down to easy reach, handy for harvesting!
Cheers!
[edit] You can see one of the risers at the far end of this shot - and a "prop" I had to stick in the middle of the suspension line mid-season to take most of the sag out of the 40' line.
