I bought a pair of Silblades, probably a year ago now, and I think they're the best blade I've used yet. I've tried bosch, the cheapo's from wally world, etc. these ones are made to last and leave an extremely clean windshield. Built to perform in poor conditions and sustains quality against the elements. Fairly positive they also come with a 5 year warranty. I picked them up off of Amazon prime for around $15/ea I believe. You can actually go up to 14" without any interference on your windshield. That's the size I run right now.
