For the benefit of those bros and sisters looking at the original bosch aerotwin wipers (those flexible, one piece rubber type), I just found a contact selling a retrofit version (courtesy of VAGSG forum). Details of the stockist provided below. Anyway, the retrofit is suitable for those NOT looking at changing the entire wiper arm. It can be used on normal 'J' clip wiper arm. Cost me around $78+ inclusive GST. Only bad point is that the wipers comes as left-hand drive version, so the aero-spoiler is facing the wrong way. And....the retrofit attachment is quite a chunky piece, so not as sleek as the original Bosch wipers. No chance to test it out yet, so can't comment on the usefulness during raining session. However I did try it out using the washer water, verdict so far....super smooth, super quiet, super clean.....but then again it's bland new, so not a true verdict on the product.
