BarTT Teesside is a busier unit than Doncaster. Not only this there is a higher volume of ga traffic in and out of Teesside then Doncaster, also one of the main operators at Teesside is FRA and they operate more like the military. On top of this there is RAF Leeming's final approach crossing Teesside's final approach as well as all the military flying in the Vale of York.
Also LPL took on Doncaster at low levels of traffic, too take on Teesside at LPL would be completly different as at times Teesside needs 2 controllers on radar. This would more than likely mean recruiting more controllers at LPL. I just think with my limited knowledge moving the radar unit from Teesside to LPL would be a big mistake.
