Centaurus, I speak as I find and my experience showed me that a significant number of the experienced pilots were harder to train, ex forces or ex air taxi made no difference it wasn't generally a lack of ability but an attitude problem. Most listened learnt the SOPs, the flight profiles and checklist responses and arrived at the sim looking to learn and do the best they could, taking this attitude into line training, others were far to keen to explain that they didn't do it that way on their previous type civil or military. Your MU2 aviator sounds like he would have been a pain in any sort of aircraft.
