I seem to read alot of negative comments about fiberglass poles. I have used them for years now without a problem. The first tent I bought that had them ,I thought I had died and gone to heaven! I used to always bend the Alumn. ones. I have had fiberglass bend under severe wind loads and never broke any, if they would have been alumn. they would have bent. I have also had Alumn. poles get bent it storage/travel. So to get to my question, why do you use alumn. vs fiberglass tent poles? What are your experiences with failure of either?
