Homer, I can answer one of your questions. FL200 lvl 10nm b4 Monty is the Standing Agreement between London Sector 5 (Brecon) and Manchester West Sector. Manchester West have to then get you below FL195 BY Monty, otherwise you enter another Sectors airspace (S29). It keeps everyone happy the way its done, and as the STAR chart starts at Monty, the restriction to expect before it aint written on. However, in my mind and many others, it should be for the whole descent to keep everyone in the picture.
If people feel having them all on the plates is useful, how about getting together to get them changed??? There must be a division in NATS that could help out, although new centre = new division = new name !!!!!!!!
