I prefer to have my hands on the home row. I therefore use D and F for rotation and my navigation keys are:
UIO
JKL
M<

Besides being on the home row, I also moved my nav keys off the keypad because numlock isn't very friendly with my laptop, which was sometimes in a docking station (with a full keypad) and sometimes not. On my laptop, numslock turns a lot of the alpha keys into number keys when not using a docking station, which is a bit annoying.
I'm simplifying this a bit. Those keys are the proper keys, when looking at the keycaps, but since I use the Dvorak keyboard layout, they actually normally do other things. I.e. my rotate keys are actually "
E"
and "
U"
and my nav keys are:
GCR
HTN
MWV
Yeah, that was a bunch of detail, but you asked....
