Thanks CAT3 - and just out of bed?!
A little point that might be of some interest btw...
Obviously you get published SID/STAR which are official....
but a little unknown thing that was made aware to me in my IMC (thanks Stuart!) is a 'Contrived SID/STAR'. This little gem is not an official SID/STAR but however it is the accepted training procedure for the airfield (This is true of Cranfield - not too sure about Stapleford but will find out for you!)
Hope this is of some help with the discussion with your captain CAT3!
