The technique(s) used depend on the scientific question(s) being posed before
doing the simulations. If you expect some reactions, etc. to be taking place,
then you need QM/MM. If you just want to simulate a peptide over time, then
plain MD is fine. Methodological details like this should be decided long
before one approaches a keyboard :)
