I'd agree with most of the above, including owning a Triumph ( '75 Stag ).
If your passengers are willing to fly again, that's one of the two dealt with. But do you brief them on safety procedures etc
As for the pilot part, it's hard to be 100% acurate. As long as you know your limits & that you are slightly off, your a good pilot.
Unless you cut infront of me in the circuit!
