Check again ... list all the products from that company on the R and L
site.  You will find both the D and the F2-D ropes which are Dyneema
core (similar in performance/strength to Kevlar).  The problem - as
explained to me - is that although Dyneema will not stretch under
dynamic load it will "creep" (slowly elongate) under static loads
like those encountered in guying applications.
