Certainly no one is going to argue with your philosophy of improving skills and demanding professionalism. Does this ATP program result in a IFR or (VFR only) rating? We had a few guys get the ATP (VFR) and I couldn't really see what the advantage to that was except possibly for status.
Do you file IFR and fly IFR during your operations? If not the proficiency gained during the training will wane as time passes.
