I was lookin at PIAA.com the other day and found that they sold full sylicone wipers. Are these full type just for the sake of saying you have them or do they actually improve anything? My wipers on the first swing i guess you could say are fine, its the coming back down. they like to jump a lot and end up leaving things just as bad but with lines all across my windshield. Or are the NAPA wipers or whatever just as good?
