I love the 42" one on the front of my John Deere GX335 which I never got to use once last year. It will blow anything from powder to gray slush water and doesn't clog up. Hope I get to use it once or twice THIS year!
(I hope you didn't mean only walk behind blowers...)
Well, I'm hoping the one in my Avatar, most of you know what I did to get it to this point. But so far the 37A on my 212 did an amazing job and I was very pleased with the fact that if it "clogged" it would always break free on it's own with just a bounce on the ground!
