Joe,

I agree. What ever causes the least friction on the exit holes in the fuse. I have had some crossed, and some straight. Ideally, I have found that if you can run the cables through small nylon or teflon tubing at the exit, it greatly enhances the smoothness of the rudder and no wear on the fuse. But unfortunately, that is usually only a luxury afforded to building a model from scratch because you have access to the inside before the formers are installed, and you can sand the outside flush with the fuse before covering or painting.
