@FoDaddy: I don’t know why the discrepancy in our experiences, just relating what has happened to me. My old car has a fairly curved windshield and the Trico blades seem to keep hugging it better over time, maybe that’s it. Ancos would usually start streaking in a couple months with this car. I put a set of Tricos on my newer vehicle about a year and half ago and they still work like new.
