Thanks for the advice, chaps. No, I'm not put off at all.
Maybe a little peversely, I quite enjoy the R/T aspect of my flying and take pride in attempting to get it right, balanced and professional, so I'm always keen to take on board the advice of controllers.
I know you guys are often busy in between the R/T calls, so no problem there either. Rarely hear any snoring in the background...
