I wasn’t trying to bark up any tree at all. I just wanted to create a discussion and see what was on peoples minds. Maybe give others who read this some ideas. I myself am a fan of the expensive Bosch Icons, they last me at least 2 years, and I replace them out of default. I know some people, like a friend of mine, who doesn’t replace the blades until the rubber is practically ripped off, and replaces them with awful ones that last 2 weeks anyway. Its just what he does.
