I might be a tad strange lol. But I use Spyder wire. I do believe it is a kevlar based fishing line with zero stretch. And at the servo end i just tie it in a loose knot and hit it with CA then I run it back to two very small control rods of which I put a u bend in them and attach it there and run it back through a very small piece of brass tubing a couple of times and crimp it and CA it there and on the threaded part I put a little nut and locknut so it will stay in place where it is adjusted and can still be loosend for adjustment as needed.
Okay another way to skin a cat
