Accelerated MD + implicit solvent. In my opinion, that might cause too
many distortions. It's a good start to get an idea of the accessible phase
space but whether that will really tell you the most likely conformation
nobody can say for sure. I would use regular MD in explicit solvent
coupled with something like REM. But that is just my 2c.
A good start would be to simply run two MD simulations in explicit water
at 300 and/or 310 K (50 - 100 ns) and see what those loops do.
