Ray,
Thanks very much.   I guess that rotor cable would be too lightweight?

I know that this tower design has been around a 
long time - I didn't realize 40 years.  The winds 
are mostly gentle in my area of S. California so 
I'm hoping for 65 feet extension without too much 
sway.  I'm putting a Steppir DB18 (96 pounds) on 
it.   I will be able to supervise my tower 
traveling up and down outside my shack 
window.  The shack is just 20 feet from the base.  73, Howard W6HDG
