Don't know if I posted this recently or not, but I use Plexiglass or 
Lexan and two hole saws to make a disk that just fits over the section 
where I want to mount the guys.  I cut the OD first, then use the center 
hole as a guide for the saw to cut the ID. I mark off the location for 
the guys at 120 degrees and drill holes just large enough to insert the 
guys.  either 1/2 Lexan or plexiglass (2 1/4" sheets epoxied together 
will work) for taller and larger verticals or just 1/4" thick pieces for 
40m 1/4 verticals.  1/4" should work with 3/16 line for 66' verticals.

I run the guy line through the holes and tie a half knot or square not 
in the end just to keep it from sliding back through. On the AV640 and 
40m 1/4 wave verticals I use 1/8" or 3/16" line (which ever is handy) 
and 3/16" double braid for taller and larger masts such as 66' for a 1/4 
wave on 75.  a 75m mast gets pretty flexible.  A bucket that goes up 40 
feet would make standing a 75m 1/4 wave on end a snap.  The 3/16ths to 
1/4" double braid is plenty strong enough to hold a 66 footer in some 
pretty strong winds.

I've heard Nylon does not stretch, but new Nylon braided rope stretches 
a LOT!  It ceases stretching after it's been out in the elements for a 
couple of days. I'd not choose it for guying material.
