In my view, the only time a checklist is read from is whilst the aircraft is stationary i.e. start, power checks, pre-takeoff vital actions, after landing and shut down. I don't think single pilots should be heads-in reading stuff while their craft is in motion, especially on the ground! I'm not too fussed about the exact list of things to do that folk do as pre-landing checks. I once flew a complex type with an old ex-airline instructor (great guy). I started in on my pre-landing litany 'brakes off, undercarriage down..' he interrupted me and said 'that's enough, you've done the important one!' Incidentally, I learned at a field where only base leg joins were permitted, so got used to calling them 'pre-landing' checks as quite often there wasn't any downwind leg to do them on. I do like the concept of 'touch drills' to reinforce in one's mind that an action has been carried out or a setting is correct.
