I have lots to say about dear old EDI but lets save that for another time. What I think needs to be made clear first off is if you are landing/departing ANYwhere within the CTZ - that's up to 10DME from EGPH you MUST book in/out with the ATC watch manager by phone there as well as at your chosen site, whether IFR or VFR.
Kirknewton is run by the local Air Corps and is usually very active up to 4000 agl saturdays and sundays with thweir towed gliders and they keep a list of permitted light aircraft. If you aint on it, you aint getting in.
As for the controllers, definitely pot luck who you get. Some are very easy to deal with and accomodating. Others will have you "stand by" for up to 15 minutes to get any IFR scheduled pax traffic in ahead. These ones just cant seem to cope with mixed traffic....
Enough for now before I really get into rant-mode.
