"truck grill gaurd project" Input wanted.

[ll____b0t____ll]

Ok so a friend of mine who owns a really nice 1972 long box 4x4 and owns a shop wanted me to come up with a couple ideas for grill gaurds and he would than be making a couple of them.
He liked these ideas so well he decided to make all of them and start selling them from his shop.
I told him some input from you good folks might help him widdle down which ones to focus more on.
So please post which ones you like the most and any ideas you may have to better them or new ideas all together.

They are all designed to bolt in place of the bumbper and then bumper over them which does push the front bumper out 2 1/2 inch's.
