I started out using tree fife niner - and felt a bit of a twit as nobody else seemed to bother.
Then switching frequencies one day
contact x on 3xx.0
Read back
contact x on 3xx.0
Negative I say again contact x on 3xx.0
and so it went on, until I read back
contact x on tree xx.0
Stick with it perhaps it will catch on, it's no more daft to do things properly with your RT than it is to plan properly. Good RT, and just as importantly good pronunciation gets you places. When you hear it done right btw it sounds so much more professional, it's easy to pick that pilot out from the rest of the eers and waffle.
