I have been using Anco 3110 wipers. They have a metal body, with a plastic connector that installs on B's wiper arm.
That is what was on the car when I bought it (the blades had just went bad), and they appear to be hold up well. I have never had one slip off, break, etc., even in icy weather.
On my other B, I just bought two 20" wiper blades (I don't remember the brand), and cut them down to 10".
