Fiberglass or HDPE?

Next year I wanted to implement a mortar rack into my show. My most previous show I did all cakes, and it was great but I wanted to change it up. I always see discussions, and I wanted to know what you guys recommend. Fiberglass or HDPE tubes? I know that HDPE is going to last me longer, but it will also cost more. I was potentially going to buy one of those premade racks from AWF, but I wasn’t sure what everyone thinks
