K-30 # of AF sensors used

In reading through the manual, it appears you can choose to use only the center AF sensor, 5 AF sensors, or all of them. Does anyone have any advice on the some/all AF sensor choices?

I usually just stick to the center AF point. 11-point af will focus anywhere within the AF area, while 5-point AF will focus just slightly off-center if needed.

I was using the center point as Adam suggested, but lately I've switched to using the "Select."
BUT... I basically then turn it off (by holding the OK button for a bit), and then it functions as center point select. I do, however, have the option to quick switch to a different focal point by turning it on (again holding OK for a bit) and using the controller to select another point.

Same here. Select focus. I 'park' focus at the center point whenever I have moved it. IF I have sufficient DOF, I'm like a lot of photographers. I use the center focus to select and lock on my target, then recompose the image. I often do a stop-down preview to make sure I have sufficient DOF - I have it programmed in to my RAW/Fx button. However, if the DOF is too shallow for my purposes, I will first compose, followed by moving the focus point with the 4-way control, and finally lock focus with the smallest amount of recomposition possible. After I am done shooting that scene, I move the focus selection point back to center.

Eleven points seems like a great idea. More points is better, right? The problem is you won't always agree with the camera's choice of point. It is a gamble to use 11 points on Auto and hope the camera gets it right. I don't even know what the logic is - does it just pick the best contrast?
