I love the 07 leather on my anthracity! But some of the 06 leathers were nice -- like the leather on my Rouille twiggy.
The only leather I would have that I would call thin is my 06 Marron -- which is also dry. It was my first bag, and had I known then what I know now about leathers, I would have passed. But I do love the color, so I'm not unhappy.
Everything else seems of moderate thickness. But I think my 07 leather is even thicker than my 05 leather!
