what I have done is to secure the rod by either glueing it to the fuse or make little brackets out of strips of foam and glue it to that, if you just secure it in a couple places where it flexes your problems are gone, string is such a pain it's just not worth the hassle, not to mention the margin for error or failure they create. also goldenrod is a great control set up, it's braided cable inside a sheath and can be curved and turned more than the dubro rods, so if you have to make slight turns or curve the rods it's better, Good Luck
