Pull-Pull Rudder
I've been using kevlar for pull-pulls, and have been very happy with it - light weight and non-conducting. The only downside to it is that it will fray if you don't have a very smooth exit point at the fuselage, requiring replacement. I used a piece of teflon antenna tube for the exits and don't have the problem anymore. There are a lot of discussions here on this subject - search the threads - you'll have several hours reading.

Just a personal preference but I like Kevlar. It is very strong and stretch resistant and can not cause radio interference.
You can buy a spool of Pylon brand U-control lines made of Kevlar and probably have enough for the rest of your modeling career for about $10.
If you don't have a direct shot from the servo(s) to the rudder, you can run the flexable red nylon push rod and tack glue the Kevlar to the inner yellow rod to act as a sliding bearing. A little thin CA on one end works fine. The nyrod doesn't have to run the full length of the Kevlar, only where it might rub.
