Bloody hell, what a thread!
FWIW, I've not flown a multi-crew aircraft yet that doesn't include the park brake in the take-off config warning.
I've not had a park brake fail on in some 14,000 hours.
Remembering to release it doesn't seem too onerous a task. Certainly one that most professional pilots should be able to cope with.
I lined up & waited on the runway the other day, for 2 or 3 mins I'd say. I did it because the tower told me too. I set the park brake, and am please to say, that I lived to tell the tale.
On a side note, I have had an engine fail just after take off, perhaps based on what one can learn on this thread, I should avoid take-offs in future so that I don't have another.
