FYI - trico neoforms are direct-connect to the audi mk2 TT wiper arms. Pretty much all other wiper blades require a snap-on sub-assembly adapter to make them work. Problem with that is they are usually ugly, increase the chance that they break and also cause viberation and noise. Be careful - you just cant grab the neoforms by length - you need the right part numbers so look up the year of your TT and buy accordingly. I get mine at wipers123 online and have never messed up buying the wrong part numbers.
