Cool stuff guys, thanks for the suggestions. Ain't it funny how us 1/2A guys' have similar interests? I figured the angling skills & knot tying lore would come to the surface!

Upon further review, (verified by my Sunday morning breakfast model aircraft engineer buddy Brian,) it was kinda stoopid (he loves pointing out my stoopid thinking) doing the pull-pull cables with steel-strong, zero-stretch Spider Wire when the tail boom is a small, super-light tapered carbon kite spar. If I had a hard landing or even a rough patch of air and the boom flexed, guess what would give? Probably rip off a V-tail or it's control horn. Doh! I'm thinking Dacron 1/2A control line string or some heavy duty nylon carpet thread will work better. Either of those has a little stretch, will knot well and CA locks it solid. I think I'll save the SpiderWire for a conventional fuselage application. Make sense?
