I have several lanyards made from KMIII, about 15 to 18 feet long. Mine are full 1/2 inch, not a small diameter like Jerry mentioned. I disagree with Jerry that it won't roll, at least in the 1/2 inch it will pretty well. Stiff enough to flip, too. Obviously, Jer is speaking of a different animal...9mm is skinny; great for old school SRT, but not really what Gypo is asking about if I get the gist correctly.
For most full on flipline use, like Sean I like a 5/8 inch cable cored polyester braid, but as a second flip line for limb-overs, I like my KMIII real well. And for a regular rope lanyard, the KMIII that I have made up are very satisfactory for me.
I have them set up with snaphooks on one end, and adjusted with either self-tending prusik hitch, ART Positioner, or Petzl Microjuster.
