Do you mean the textures? Or Materials? I have some AO based mat sets that I use a lot I could probably post. With some precedural things added in. Like on the cover of the P6 CE box. I really like Syd's default textures and they're very hi-res  with plenty of anomalies and I think 8 material sets, but yes variety is the spice of life. I like my women like I like my coffee, and no, not hot and cheap, just a little darker.

I also use those Kaori Blossom textures a lot for Miki which I really like. Mostly I think because of the gloss painted on the lips. I also use some custom lights I made and get some good results with the aforementioned mat sets. I sent a mail to TamelaJ asking what she was up to for Syd but haven't hear anything. I'll try to put the mats on the CP forums for download but while I did set them up for Sydney, they have literally hundreds of orphaned nodes and nodes that proabaly don't do anything. I really need to clean them up first.
