go for the fabia one.. especially if you have a roof spoiler. i believe the polo ones need trimming because they hit the spoiler at the top of the arc.
I believe that you will find it is the other way around, the skoda one hits the spoiler

.. OMG the mighty topher makes a mistake

I get discount at newport skoda if you want I can get it. You need 3 parts - Arm, blade and cap
