I have always considers it Z'ing the front and notching the rear. A Z is basically a large notch so you can consider them one in the same, at least to me. Backhalving is a lot of work that I personally just don't want to get into.

If I had to do it all over, I'd notch it just like I did. After you notch, you can just cut out the section of bed where the notch is and not have to worry about moving the floor up and crap. You can cover the hole in the floor by a simple bent sheet metal or you can get creative. I have seen on several trucks where they got some ribbed bed flooring and just made it look like the floor naturally stepped up over the notch.
