Re: Which wipers??
I had Valeo flat blades and they juddered from the day I put them on and left behind lace curtains. The catches to fit them were fiddly and didn't ever sit snug.
Replaced them a couple of months later with Bosch Aerotwins and they work perfectly, snap-fittings held the blades a lot more secure, no judder to drive me insane and they actually clear the windscreen. They do start to leave streaks above 90mph though ... better than the Valeos that juddered and got worse the faster I drove until they hardly worked at all at motorway speeds.
I think people see varying results from lots of different wipers. Buzz gets on well with Valeo blades but my car doesn't like them, don't know if it's down to the differences in the 156 and 147 or the cleaning products we use on the windscreen, the condition of the arms and springs, amount of road grime ... whatever it is there are varying results from lots of different people if you do a search. You might have to try a few makes and models out to find some that work well on your car Pea Sea but on the whole Bosch Aerotwins are pretty well recommended.
