Which is the best Bosch ICON wiper for the rear metal arm? I have Bosch Icons up front and want to match. I hear that 18" wipers hitting the spoiler at the top of the window. I measured the stock one I just took off and it's 17.5". These are the choices then:

417A, 417B, 418A, 418B (I beleive "B" is more curved which I would imagine is better for pressure on a deeply curved window.

So I'm thinking 417B? Any thoughts anyone?
