the way I've got it is center group, which is the center 9 points or just the center 1 point. This is what I use when using the viewfinder.
With live view I put it to quick mode single, where it flips down the mirror and use the center point.
I switch between that on the flex zone single. Although I dont really like that it continusly auto focuses even when im not ready to take the shot. It is just using up the battery. But I don't really take a lot of shots with live view. So it's a non issue.
In video mode though I switch between face detection and tracking and flex zone. That's where the duel pixel af shines and where you'd actually need to be focusing the whole time.
Was that what you asking? Im still getting used to what kind of focus I like using. But on jobs im looking down the view finder 96% of the time. Unless im using high or low angles
Ah, interesting. In live view, I seldom (read: only used once!) use the quick mode single focus because the mirror slapping around is just too annoying for me--whenever I use live view, I just manual focus with focus peaking.
I was referring to usage when using the viewfinder cause that's how I usually use my camera but information about usage during live view mode is great!
Sometimes when I hand off my camera to someone, they get all confused about how to select a focus point when using the optical viewfinder despite my best attempts to explain to them how to use it so then I switch it to liveview mode. However, it's painful to watch them try to focus the camera in that mode cause it just takes so damn long to lock focus then shoot cause it's too busy stuttering back and forth! As per dpreview's video linked below, I'm glad to see that 70D's dual pixel sensor solves this stuttering.

Back to usage via the optical viewfinder, do you any of the 8 outer AF points? If so, how do you select them? With the T3i, I had to hit the upper right button on the back of it then use the directional buttons or the main dial to select them. According to a friend of mines, one can use the directional buttons on the 60D to select an AF point without pressing a button prior to that. Does that carry over to the 70D?
Also, in low light, do those extra points around the center help achieve focusing better than just using the center point alone?
And lastly, do you shoot raw when doing stills? If so, then how does the raw compare to the T3i?
Sorry for all the questions, I'm am considering picking up a 2nd body for back up purposes and a body that improves over my T3i in terms of AF and raw image quality would be much appreciated 
Btw, just checked out your website. That video was a solid edit, loved it!
