This Mapping was a game changer for me. It essentially gives me all my most used controls on one page, so no more constantly switching back and forth between pages. All I need is the User Page. Simple!
Here is the Layout;

User Page (Orange LED)

1-Sync On/Off (LED Lit when On)
2-Tempo Reset (Time code) This button is just a safety for me. Other people may find Master Tempo more useful here.
3-Loop In
4-Loop Out/ Release Loop (3 and 4 LED Lit when Looping)
5-4 Bar Loop (LED Lit when Looping)
6-Hot Cue 1 (LED will light up if a Hot Cue is stored)
7-Hot Cue 2 (LED will light up if a Hot Cue is stored)
8-Hot Cue 3 (LED will light up if a Hot Cue is stored)

If you hit 4 bar loop with any 3 Hot Cue buttons it will start the Hot Cue as a 4 Bar loop,
I find this incredibly useful. I feel like I have CDJ2000's that can play Vinyl now.

On a separate note the build on the RP-8000 is amazing, the pitch fader is like butter, and they look absolutely amazing. I have them set up traditional style and they are the exact size of my Pioneer DJM 850. I don't use Traktor Effects, I find my Mixer is better for that, so for me this is the perfect set up.
