They have lighter ones made out of mylar now, but I've never used one. I'm in the class that doesn't like them, because they're such a PITA. You need a really stiff rod to stand up to all the pressure the water puts on the blades, they get in the way of fighting the fish, and you have to keep up a pretty quick pace consistantly while trolling or else they sink and foul on the bottom. They're pretty much a magnet for weeds, too.
