I got a pair of those aero blades like mk4 golfs etc have. I forget the manufacturer now but they pop straight onto standard arms and still clear the windscreen at 100+
They're not perfect but better than the standard style ones that float off at about 50.
I seem to remember either mk2 Scirrocco or Lupo wiper arms are meant to be good. Perhaps it was a mk2 scirocco motor and lupo arms? ALthough that's a lot of work compared to just swapping blades, lol
