Thanks for the reply Adrian. I've sent a PM.
I've done some (very dodgy) Photoshopping to put the Hanzo's on some sample internet pics of a gunmetal Zed side on (easier to do) .
I'm interested to see the colour against a gunmetal Zed as I wasn't sure it would look as good as the white Zed which, in my opinion, is hands down the best colour for the Zed.
The first pic is my Zed, the rest are internet sourced. What do you think?
