ever since iv'e owned my car i go through blades faster than a baby goes through diapers. i mainly shop at autozone or wally world for them, but they always run crappy after a month or so. i also checked out the springs and someone told me that they seem too tight, i don't know, i was thinking on taking them off and loosening them up. what kind of blades are out there that work the best in your opinion? thanks.
