I always enjoy flying with other pilots, if I'm P1 or not. I always learn something, and it's no bad thing to see that other people do dumb things too sometimes
Plus it helps to have a navigator when you find yourself somewhere unexpected, eh Speedbird252...

I hope that other pilots who I've flown with have enjoyed, and benefited from, flying with me as much as I have with them.
it makes me think back to Sywell. FFF gave me control and then 'failed' the engine on me... really enjoyed that
but at least he didn't criticise my rubbish PFL
