I like the Icons as well. I have the Micro Edge's on my e36 and while they do a fine job, they didn't last nearly as long as the Icons on my X5. I also like the built-in spoiler of the Icons. Seems to help in very windy conditions as well, not just vehicle speed. The other thing about the Icons is that due to their design they seem to make better/more even contact over the entire surface of the blade.
