I decided to run a fully pull pull system on both elevator halfs and rudder. I ran all my wires and I got to looking at it and I am noticing that with 6 wires all running back to the tail they half to be touching and rubbing together, and they are I can see. I was wondering if that is ok to leave it be or should I separate the wires by running them through plastic tubing as they cross through the formers. That was one of my other problems, In order to do the top half of the elevator, there was no other way but to curve the pull pull cable up so it lined up on the top of the elevator. That particular wire is rubbing against the back formers and up through the top of the plane, I was definitly going to put that portion of the cable through a piece of tubing. What are your suggestions?

Thanks,
David
