Please don't abbreviate whowhenwhy to WWW as it confuses the heck out of me thinking I have been contributing to threads that I haven't even read yet...
Anyway. I always thought RAF Shawbury were very fair with their limited RIS - they would downgrade only when they were balls out or you were 3 counties away. Bristol Lulsgate do a similarly admirable job and their propensity to offer services even when busy ultimately improves the known airspace picture I find.
LARS needs more financial support as the UK FIR gets busier every year. The cost of infringements at the likes of STN and LTN alone mounts into tens of thousands as aircraft are held and vectored and TCASd due to light aircraft not enjoying the luxury of a good LARS.
Theoretically the owners of NATS would spot this fact but being beancounters they probably won't.
