ultimately, standard phraseology is paramount, Stand up - Speak Up - Shut up.
Couldn't agree less. The old saw is "aviate, navigate, communicate". When (if) you must communicate, stick to standard phraseology, but, if there is a *need* to communicate, and you either don't know, or there isn't standard phraseology to do so, just get the message out in the most concise way you can think of.
There's more to flying than being word perfect on your R/T. Not to suggest one should be lax, but it is a long way down the scale from paramount. I'm currently minded of taxiing in from a flight listening to a guy at the pumps deliver a perfectly phrased spiel - then taxi forward into an iron re-bar which was holding up the red and white striped "don't go here" tape..
