I've had two fiberglass shells on two previous trucks. One was a Leer and the other was a Snug Top. I liked the Snug Top better than the Leer. Neither one of them was very cheap however. Snug Top had better fit and finish.
Just cause it's loud doesn't mean it's fast and just cause it's shiney doesn't mean it's protected. Remember, going fast costs money, so how fast do you wanna go?
