Thank you Novitec for these serious pictures, you too are fond of alloy wheels!!! :-)
My favourite are OZ Superturismo, very similar (even as colour) to my Team Dynamics 7,5J x 17 ET 25 I used to run two years ago.
I guess they are the lighest rims of all.
Second choice, BBS Le Mans (I agree with Jazik, perhaps if in 17" even better).
Third, BWA star wheel... a big classic but much less special than the other ones.
Orobica, in my opinion, are not bad at all but maybe much too "modern" for our car (in this case too, I would have preferred 17"... if available of course).
