Anthracite with RGGH is a
gorgeous gorgeous combo. btw...All the 2011 bags I have seen in this combo do not have the greenish tint like a lot of the 2010 bags do.
I've not seen Gris Tarmac IRL but love the pics I've seen of the RGGH 12 combo. I've been tempting by this combo many times

. It's such a pretty dark grey and I like it with the smaller hardware.
I'm one of those that was not fond of Parme in the past. I don't think I gave it a very fair chance though. When I saw it I was looking for a light pink bag (something more like Bois de Rose and was disappointed that Parme was not more Pink) ....it's definitely more of a neutral color. If you are looking something neutral with a small touch of pink/lilac then Parme may work for you.
Good Luck with your choice!
