Mun or Minmus for resource bases?

[TheXRuler]

@reguia I see what you mean, however if the orbital period is your problem start your mission well in advance like three months or so, I do this anyway because it provides me wiht ample time to test the vessel, send up anything I might have forgotten, refuel, test some more, and most importantly plan my burn(s).

In fact what I often do is launch the vessel when I have a cool idea for a mission (which might be a year and a half before the transfer window) then add and subtract things as I see fit, (yes my plans often change after mission launch xD)and most importantly plan things properly, that coulpled with laies ingenious idea of using a probe for manouvre planning and an idea I just had should make it quite easy really.

The idea I just had:

Refuel at minmus, set up a monouvre with the probe, figure out how long it'll take to that manouvreand set your orbital period accordingly, then when on the new orbit lower your PE at the correct time and enjoy the oberth goodness
