I don't know about the fiberglass but I would use Phillystran HPTG1200I for 
the the Quad stays.  A bit pricey at $0.49 @ foot and $4 per end, but you 
only have to buy it once.  I had an antenna that would either stretch or 
break the boom support rope in the slightest wind (lots of sun degradation - 
Texas).  Replaced with the Phillystran and never worried about it again. No 
stretch, no breakage & no worries.
