i think the OP wanted to see images indicating example of what all the drama is about relaing to DxO numbers
since this thread has hit 7 pages and no images have come forth it kind of proves what a non event the whole issue is 
I am OP (and posted one landscape shot)
You hit the nail on the head. I don't own any ND filters, just the 5d2, 17-40L, and some UVs and cir polarizers. I need to invest in some ND grad filters and practice, practice, practice.
I agree there are too many chiefs and not enough indians on these forums. No offense to Native Americans. I wanted to see examples of shots that could benefit from better DR, or that demonstrated what DR could do. I guess my strategy got thrown out the window. Or did it get vomited into 8 pages? You be the judge...
