Bravoexo, I think your innovision doest shake as much not it’s lighter in weight. In fact, I believe that a heavier blade can contribute to more stability (weight pushing against the windshield). Weight has got nothing to do with it.

The innovision, according to popular mechanics:

"Innovision is the first aftermarket jointless (one-piece) wiper blade. It's engineered to follow the curves of today's car windshields, it's more resistant to ice and snow buildup, and its low-profile cross section reduces wind lift at higher speeds."

Look at Trico Innovision:




Another great brand, VALEO (bravoexo posted this a while back?!)
