Ok guys... I think I will stick a fork in it.
What I did was fix up my 10ft section (was horribly disfigured when I brought it over from SU), re-textured it so it can use higher resolution textures, and added it as middle geometry to a loft. I will not be adding the rubber padding (I've sat on this long enough).
What do you think?

left we have fairly new, middle with some rust, right is that textured concrete from the photo earlier in this thread.
