I need to buy another 8 foot step ladder since I damage my fiberglass ladder. I have been reading the cons and pros about aluminum vs fiberglass. Which one would you prefer and why? I need to replace an 8 foot fiberglass ladder. I'm considering a aluminum ladder because of a foldable shelf, ligher and cheaper. None of the fiberglass ladders have the shelf. The only electrical work I may do with it is changing out light bulbs. I never owned a aluminum step or extension ladder. All of them have been fiberglass.
