The back window always is dusty and it seems to be harsh on the rear wiper.
12-A works, too, however, it's not an exact match. I liked the look/style of the Ford-spec'd Valeo better, so I transplanted the insert from the aftermarket blade to the original.
I did use Gen2 blades for a while but switched back to the Motorcraft-spec'd ones. The Motorcraft blades, while built by Valeo, have a more aggressive wind spoiler built in, and aren't bi-directional.
