As I said, there are two confused issues here; they should have been two threads.
I was not IMC over LKH, though I did have to stay as low over the MATZ as I did in order to stay VMC. Hence I wouldn't have wanted a RIS from Marham, only a FIS, and as you rightly say, but I didn't think about at the time, they would have known what was going on at STANTA.
However, it was Niknak's comment that 'We would have provided you with an FIS, but not not much more due to our own traffic levels, I doubt that Coltishall would have be able to proffer much more, and realistcally I don't think Wattisham would have been able to give you a service' that led to a dubiously related diversion about the level of service available from LARS units to aircraft in IMC but outside CAS. Red herring as far as LKH was concerned.
Hope that's all clearer now...
