Best roof rail/rack solution for D2 A8

[Dezzy]

I'm home this wk-end and i have to get the camera out for some other 8 photies so i'll take some of the bars i have. The ones i have don't have as much contact area on the roof, they sit on the raised part only on the outter edges of the roof.

Also yes they are quite square although i didn't really notice any more noise. But the box i picked up that is meant to be genuine had the fitting kit with it and that is Thule, u bolts come up thru the box and a twist type locking doodar that clamps the u bolts thread, i don't like it as there isn't much engagement on the thread and i'm assuming because the bars are quite fat.
I have gone with a new design called washers and nuts, i'm not wanting to blow my own trumpet but i can see it catching on.
