If you are familiar with Project Farm, he tests all sorts of things like oil and such. This one is actually really good as I have never seen a true comparison of different wiper frame types.
I have always used metal framed blades as I could never justify the extra cost seeing that I would replace them twice a year, using winter blades (old style metal frame wrapped with a rubber cover) and summer metal frames. Years ago I was disappointed with the beam type but that Bosch might just convert me. And if they last a whole year as they seem to be good for winter, it might actually save me some money.
