Well, I have to disagree here.
I've used all sorts of PVC tubing and have had no failures at all. 
From white to dark gray and even e few "happy coloured". Not even a 
sign of carbon tracking.

Acrylic has worked very well too and also fiber glass tubes. You can 
use a hot wire to cut acrylic and then sand the rough edges as an 
alternative to sawing.

I even have a secondary built around sonotube (concrete form) *WITH* 
print. The paper is well impregnated with oil but it works excellent 
(4kVA+ and long runs). Although it's not recommended with print I've 
been lucky.
