Pace:
I can well understand your personal reluctance to fly single piston aircraft at night but has it ever occured to you that the Royal Air Force did this for years and years and years with very little problem?
I myself, did many hours at night in the Piston Provost behind an Alvis Leonides engine which had a lot more moving parts than the average Lycoming O-320.
Indeed, towards the end of my 50-odd years of accident and incident free professional flying, I used to get a great deal of enjoyment out of going night flying in my PA-28.
Each to his own taste.
