Is not exactly an epic but it is long enough and it is what ATC seems to expect. They, certainly tend to ask me for supplementary information if I miss anything, which seems a waste of time.
Anyway, I am certainly not an expert and only really repeating what I have been taught but I can see some benefits to a very concise initial call, especially on a busy frequency.
