Manrow,
I'm so glad you have nothing against us chaps (and chapesses) at Manchester. As far as I am aware, a few of us controllers haven't cast our eyes over this one, either this time or the last time it was "trialled". Alas, on that occasion the trial was somewhat negated by the closure of D5 for taxiway repairs. Better luck this time. It is an airport company trial of which we have been made aware.
