Watch Prestonfield , not landed there myself but the site is not huge and is surrounded by tall mature trees ,the site is bordered by a built up area and a Golf Course . Not good if going in heavy . I'd say a twin for public transport flight. Interestingly the head green keeper of the Golf course is a friend of mine and a couple of years ago I was going to take him for a flight from that site and the chief pilot of a local company at the time who knew me and my experience well said no that it was a too congested for a single. Having said that I have seen an R44 land there so who knows.
