JD, no I am not joking. I can see why standard OHJ would not work if there was another field nearby. CLJ gets around this problem. Check your Pooleys for Sleap airfield. As for your comment it is "totally non-standard", I really don't know what that means. It is a legit (and practiced) way of approaching a field with the circumstances described.
JohnGV, welcome to the UK and busy airspace.
