Surely Custodians is a reference to the people/club who manage and look after a course, and making Ran's 147 picks is a reflection on how they did that. Therefore in relation to TOC or the Eden, the Links Trust would be the custodian. Mark's point is that they haven't done a good enough job.

Yep, that is my take at least for Eden. Despite my disappointment with the Trust, I might include TOC on my list. Ran obviously does. The New would make my list.

Sean,
I don't see how you can identify the same body as custodians of the game for the way they have looked after TOC and dismiss them for Eden. Ran's selection of a course as a custodian doesn't really make sense, surely the custodians are the clubs/owners of the courses listed? If Ran intended to identify the Trust, then I think they are disqualified by their "care" of the Eden and his inclusion of TOC was a mistake.
If, however, the list is really intended as a list of courses which demonstrate good custodianship
of a course, rather than the game, then I can see TOC being included, as, in respect of that course, they have done a good job.
