Cuddles - can you explain how this might affect helicopter services ?
One of the main reasons for moving Sector 33 ( and later S7/31) is to allow LACC to do further resectorisation of the airspace where the big delays occur. There wont be qualified enough staff at LACC to do this and all the existing sectors. ScACC's staff projections allow for this expansion to take place.
It also helps balance the size of the centres when you combine all this and MACC, in Prestwick, you get a substantial sized unit at both ends of the country.
