Jollyrog....
Never used East, just North and Classic and have to say whenever I've wanted them to provide a RIS always been there, sure there are times when they're busy and Sunday afternoon with all the weekend traffic isn't the time to talk to them.
Would have much preferred the '0013' Luton approach where I know they're watching and they know I'm listening.
"Only on quiet days..... when the sun is shining and everybody is out then a request for a RIS is often met with FIS due controller workload/radar clutter/poor radar performance or some other random excuse.
Sorry to say that the days you really need it, when the sky is black with PA28s out of EGTB and EGLM, you don't get it...."
Sounds like Brize, Benson and the reason why Luton stopped LARS service.
