A cool (back) skin for the I+Case aluminium case?

[colourmaker]

Hi, I am lucky to be one of the backers of this project, and I have ordered a silver version of the I+Case.

For those curious: you can not get into this project and order a case now,you had to become a backer before 15th November.

I have the European version of the 4S
I am looking for a cool skin to complement this bumper.
I am considering one of these:
Lucky Labs iPhone 4 Tru Skin Black Carbon Fiber
Lucky Labs iPhone 4 Tru Skin Silver Fiberglass
ifixit iPhone 4S Transparent Rear Glass Panel
Trunket American Rosewood - Sea Blue (just use the back skin)
Trunket American Rosewood - Jet Black (just use the back skin)
iPhone 4S Metal Back Cover - Grey from SW-Box
Gunmetal from cnn.cn
maselements Black PVD iPhone 4 Titanium Back Cover
maselements Patch iPhone 4 Titanium Back Cover

I backed out from this project after hearing bad reception from draco iv cases. Didn't want any drama on returning process.
