Any force field that needs to use conformation-specific parameters to enforce 
some geometry is a bad force field.  Thankfully, I know of no force fields that 
do this.  Proper force fields will correctly sample conformational fluctuations 
that reflect the real ensemble of the biomolecule in solution.
