That's why I avoided the 'S' word; SERCo don't seem to have too many radar rated ATCO's for airfields, and where they do, they seem to discourage them from actually using radar, presumably so that ADC and APP can be done by the one controller.
As a 'radar only' approach controller, I have a great deal of respect for 'procedural onlys' considering the amount of traffic they can shift without radar.
