Much as we only notice those with a massive chip on their shoulder about not being ex-mil, how much better they are because they worked on the N Sea, and how no-one could learn from ex-mil (arrogant) pilots - because they keep banging on about it on these pages.
Post-PPLH mentoring is a good idea and most of those without egos on here recognise it - it doesn't have to restrict their freedoms or cost a fortune, but it is a good idea and those that want to learn and improve will - those that don't won't but they will probably be in a minority.
