At getcoolparts you can get the floppy ones bosch wiper arms for like 26 dollars. It includes the insert and it works perfectly. Remember that there is a coupon Audi06 and if you buy 2 pair (I think) you can qualify for free shipping. Audi06 takes 5% off and no tax in california.
I don't think the Aero wipers work. I believe that you'll have to get the ones with the wishbone type supports if you have the old style wipers. These are probably the ones that the original poster is discussing.
Bosch Icons are your option for fitting the aero-style wiper blade to an older style (J or U-hook) wiper arm. I have fitted them to my 2001 Audi TT and my wife's Ford Escape, they fit and work well, and have a much cleaner look that the standard bracket-type arms and blades:
Just picked up a set. Cost $40 at autozone. They are just like the aero wipers but for the hook style as someone posted above. So much better than stock. They were one of the best mods I ever did on my old gti. My wifes jetta is getting a set today
I used to buy the strip for like 2.44 at walmart then they stopped carrying tripledge. I then used the ones they bought for replacement. The first time I did it, it worked fantastically. After that it chattered like crazy. I'd almost pay 23.xx for a good set of wipers each year.
