You are correct, and there really is no straight answer as everyone's setup is different...

I do like to keep my guiding and imaging at similar resolution.. that way if I monitor my guiding graph, and it says that the RMS movement of the star is .2 of a pixel, I know in my image it is less that .2 of a pixel, and there for, its going to make a nice image... Currently using an OAG I've got 5.2um pixels on the guider, and 5.4um pixels on the imaging camera... The guiding is always tighter than 0.3pix correction distances, and I've not lost an exposure due to guiding errors in months..
