PVC is not nearly as strong as fiberglass, and PVC is VERY sensitive to 
UV.  It gets brittle after a year in the sun.

I found 1.25" solid.  That's what I have now.  They could have ordered 1.5" 
for me, but they had 10' long 1.25" in stock, so that's what I took.

I bought mine from Ridout Plastics in San Diego.  www.ridoutplastics.com or 
try your local yellow pages for a plastics store.  Looking at their web 
pages I see that they have a UV-resistant version of fiberglass too.  Too 
bad I didn't ask about that when I bought mine.
