Fiberglass vs. metal

I have restored many mopar musclecars over the years and never used fiberglass body panels, I always refinished original metal panels. I am thinking about using fiberglass fenders and hood on the 70 340 Swinger that I am currently restoring. I have seen the products from AAR Quality Fiberglass and it looks really nice, nice and straight, nice heavy weight and crisp lines. Their stock flat hood has great detailing underneth and installing the original scoops wouldn't be hard. What do you guys think about using glass parts instead of steal ?
