[amsat-bb] insulated mast??

Just a curious question.  I know the insulated el. boom subject has been beat to death.  I happen to have five, 5 foot fiberglass boom sections.  Is it worthwhile using one for the mast??  I used a metal mast for years and it "seemed" to work fine for me.  Having a plethora of hardware for my satellite antenna rebuild.
