PS I'd like to add that I did drive back to back at the factory a supersport and an aero plus 8 like Peter's one.
It remains vivid in my memory as I had Steve M next to me. He was very restrained when the supersport started to go sideways (I say the road was greasy) he just said "we've only got one of these you know" for which I admired him.
I didn't enjoy the supersport but I thought the plus 8 aero was fabulous. All the right sounds and traditional feel.
I do hope you keep yours Peter, though my betting money is on you going to a plus six...
