I just returned from Gander Mountain and they had some real nice black nylon coated stainless steel cable and crimps for making a pull-pull set up. I have always used 60-pound leader material but while I was there the 30-pound looked like a better size. I flying 90-120 size aircraft with 168-ounce servos, I would think 30-pound (480 ounce) cable should be enough. What are you using?
