Constant Velocity SMD Question

  In your opinion/experience, would it be more accurate to use the equilibration.restart or free molecular dynamics restart files for a steered molecular dynamics simulation? I ask because my ligand that I want to pull out of a channel takes on a different confirmation in a free MD simulation (no restraints) than in the equilibration simulation (due to restraints applied). I wonder if including this different confirmation as a starting point for the SMD would change the result of the constant velocity SMD, and if that would be more realistic than starting from a restrained equilibration confirmation...
