Looks like you and your girlfriend are halfway to choosing a helmet already.

But, your reply illustrates the problem quite well.
There are lots of different helmets and lots of different heads. So what appeals to (and, more importanly, fits) one person is totally unacceptable to another. For example, the Nolan flip-front. It's quite popular. I tried one in a shop (it was in Motowardhus in Stockholm, forgive my spelling) and it seemed OK. I bought it, but I hated it on the bike. I sold it to a chap on UKGSer, who thinks it's great. We are either both right, or both wrong, or somewhere in-between.
Helmets, are rather rather like eating fish and meat. Some people do, some don't and some are fussy in-between.
I totally agree, thats why in my first post I named a few helmets that we have looked at, and are interested in. I dont mind at all if people give their thoughts on other helmets I would love to hear what you all think of different helmets. But the ones I mentioned in the first post, are the ones we have tried on and liked.
My girlfriend tried on the different styles from schubert and bmw. She thought the schubert C2 was a very big helmet and it didnt feel right on her head. Same goes for the schubert concept. The new C3 is a smaller helmet and she thought that fit was very good.
The system helmets from bmw fit her head very well also, but the system 5 is not an obtion since it does not have a sunvisor. The new system 6 does.
The Airoh helmets also fit her head well.
The shark helmet we actually havent tried, have just heard from friends that they are very happy with their shark helmets, and the ones I have seen seems very well made.
Both the schubert and bmw seems very strong and good made but are also a lot more expencive. The airoh seems cheaper made and I dont know much about them, dont know any who own one, so I wanted to hear from people who have or had one.
Is the higher price eaquel to higher safety? Or are schubert and bmw so expensive because of their name?
About the roof helmet i own. I got it about 6 years ago when I got my first bike a yamaha xv drag star 650. And I really wanted an openface helmet, and the roof classic is an openface helmet with the option to be a closed helmet in rain and bad weather

It also fits me well. My opinion on the helmet is how ever that even when closed it will not be much safer than when open if in a crash. Thats why today, an a bikecrash experience richer, I wouldnt use this type helmet again. And thats why I dont like it. My girlfriend dont like the looks of the roof helmet designs and want to ride with a closed helmet all the time anyway.
She doesnt like Noland and caberg helmets, mostly because of how they fit her head.
