Trico has just come out with a new blade that is also completely incased in rubber. It also does not used the segmented wiper blades that most other companies sell. Theirs has a molded in spring steel arch that puts even pressure on the wiper blade so you don't get a streak where the squeegy blade connects to the wiper blade segments.
A great way to get smooth, clean and quite wiper action is to clean your windshield with a good Auto glass cleaner, or use Barkeepers cleanser. Once the windshield is really clean, give it a coat of Rain-X. With Rain-X, water just rolls off the windshield, and wiper blades just glide over the windshield. Since you don't have to use your wipers very often with Rain-X, the blades will last longer.
I typically change blades about every 6-9 months when I use Rain-X, however without Rain-X I have blades go bad in as little as 3 months in our Texas heat.
