Whatever you do,
don't get the Valeo aeros from
www.wiperblades.co.uk - they squeak like crazy & it doesn't matter if it's a monsoon, light drizzle or snow.
Bought some VAG 'aero upgrade' wipers from a VW dealer - the Mk4 Golf/Polo's fit Leons - for £20-ish (cheaper than the Valeos at £28). They clip onto the OE arms, look good, clean brilliantly & are silent.
