Which windscreen wiper for an X308 XJ?

[Baryonyx]

Afternoon,

I'm after getting a replacement windscreen wiper for my 2000 Jaguar XJ. The current wiper fitted is in good shape physically, but it just doesn't clean the screen very well. I did read somewhere that these cars are quite wiper specific due to their curved screen. This one glides silently over the glass but seems to have a poor contact and leaves the glass smeary, even on a freshly washed screen.

Any recommendations for a replacement? I'm loath to start buying wipers trying to find one to fit, especially since they all seem to come in packs of two!

Thanks for the comprehensive answers guys. I may give the aftermarket replica of the original a spin from the supplier to see how that works. It's not so much that the ends don't touch down and it wipes a clean spot in the middle, rather that it just leaves a wet smear across the whole windscreen. It is silent though, so it's not catching and dragging. I'm going to order a new one (it's currently wearing a Bosch blade) and clean the screen with methylated spirit and maybe give it a RainX treatment.

The car is getting it's first car package this week, new wiper blade on the front and two new tyres on the back.
