Steve & Others,
We all set up our engines in such a way that makes us feel secure, and no criticism intended, but I wanted to emphasize a couple of points for other readers....
You mentioned that you don't switch the injectors separately. Switching off one set of injectors is a standard part of my preflight, and it has saved me from taking off with one circuit down. Also you said that you have no fuel pressure gauge on the panel. The fuel pressure reading on each pump is also part of my pre-flight. During the first few hours this helped me detect a blocked filter and a bad pump ground, and once helped me solve rough running in the air.

Extra switches and dials in the cockpit certainly increase pilot workload, but they sure help with problem diagnosis prior to and during flight.
