I wanted a modern Rock & Roll, and I liked the image of the concept vault version, but not the execution, so I made my own. I was going to use the 25th Rock & Roll bullet belt webgear on him, but it got in the way of his arms properly holding his gun, so I had the shoulder straps on him for a while before adding some bullet belts and losing the straps. He just didn't look like Rock & Roll without his bullet belts!
