Oversized wind blade....needs paint.
Little changes can make big differences. I'd tried bicytcle brake cables in brake housing...too much friction. I tried thick monofilament through teflon tubing, too much friction. But I hadn't tried the brake cables through the teflon tubing, seeing as the brake cable housings are lined with teflon. Well...son of a gun. These rotating hangers mean that the wire pull is always a straight line, too....cuts friction.
And finally, adding a little bit of material here and there to ensure the cables don't rub on anything, helps, too.
