I see no sense in such a question at all. Basically, Madara's/Sasuke's EMS is their own MS from the point they awakened it through Izuna's/Itachi's eyes respectivelly. So, accessing EMS = accessing MS for them, just in more powerful form and without usual MS drawbacks, as Vladosaurus poined out. How should they use MS if they are already using it in the EMS form?
