Nothing too radical... I mapped the Level to the M.fn button, focus point selection is on the rear AF point selection button with the selection tied to the front dial, aperture on the front dial, shutter on the rear dial and I used the C1, C2, C3 positions to store focus set-ups for quick changes when shooting sports: C3 I have set up with Rear Focus, Servo and Expanded Area Surround; C2 is normal focus(tied to the shutter), Single Shot, Spot; and C1 is normal focus, Servo, 61PT. Subject to change... Lol. 61Pt is a little flakey. I've been experimenting to see how well it works handing off to other points from the initial point you select and sometimes it's good and sometimes it isn't.
