It is good to call "Vacated" to if you think it maybe difficult to for the tower or the following a/c to determine.
However, I know I have done a well judged landing if I hardly need to touch the brakes and get off at the first exit at Blackbushe
Mind you, not using the brakes on an AA5 isn't really an option seeing as it is the only way to steer. The right brake needs to be ridden lightly for a few seconds to keep it straight on take-off too.
