I always think these folk should go learn to fly a small aerobatic taildragger out of a farm strip. Nothing else sharpens the mind like being solely responsible for preparation, field state, go/no-go and wx decisions, W&B, fuelling, fitness for flight decisons (you and the aeroplane), and the myriad other stuff you have to deal with in real time as sole operator, especially if it starts to go pear shaped.
Completely agree with the "Nothing else sharpens ..." part, but I don't quite see the connection to the placement of the auxiliary gear and permitted g-loads and maneuvers.
