I have used the kevlar control line cable for pull/pull and works great. Make sure on the exits to use a short piece of nylon or equivelant tubing to keep it from fraying on the fuse. I use small eyelets on the clevis and tie it off in a double knot and a drop of thin C/A and it will not pull loose. Easy to replace a cable if it does give you a problem even at the field. The kevlar also eliminates any feedback problems to servo's like piano wire might. I encounter that one time on an all metal gear servo with a metal control arm. I used piano wire and keep getting a jitter in the servo till I replaced the pull/pull with kevlar.
