Buisness card designs

OK guys and girls its not often I ask something of you, but today I do. I've recently discovered the joy that is http://www.moo.com/  and their ability to print any number of images in one print run. I want to produce some new business cards for my trip overseas and I thought it would be cool to produce a series of cards rather than settle on one design.

There are 15 images here, but I think that's a bit excessive so I want to whittle in down to 10.

Here's where you come in. I would love to hear what designs you think work, what don't work so well and which you think I could leave out altogether. I realise this is a big ask in these busy times, but any thoughts you'd like to share will be welcome.

Thanks for stopping by.
