Thanks for the opinions guys. Very much appreciated. Great is of course a term that means different things to different people, but it's interesting to see where some of you have run with it.
Simon H: I agree "great" is overused in all arenas, much the same as "legend" and "hero".
Melvyn: Thanks for clarifying. That post appeared to be directed at Tom D, which would have been slightly confusing...
Kevin P:
What's your definition of "great" ? and what would you include in it ?
One of the reasons I started this thread was to see what others thought because I can't really pin a definition myself.
It spawned from a discussion with some Scots who took exception to me saying a Scottish Top 100 probably went too deep to be meaningful, which led to me wondering at what point do you cut off a list?
Australia has four times the courses that Scotland does, but you couldn't say our list would merit being four times as long. As Andrew said, 50 in Aus starts to include some courses that you couldn't claim to be special. Having only played eight courses in Scotland I wouldn't know how deep the quality runs exactly, other than having a pretty strong feeling that 100 is extreme overkill.
It's hard separating what I enjoy with what I think is great. I love The Addington, but is it great? Maybe the head and heart are too closely linked to try to separate what they each believe.
The "100-mile rule" as Niall notes can get cloudy depending on what else is around the course. I find myself lately when I play a course, thinking how strong the lure would be to drive to play it if it were located where Silloth is. I guess that touches on the thinking that some courses get unreasonably "bigged up" as a result of being near great courses while others in the same situation seem to find themselves overlooked. If you take a course out of its area and remove the other temptations, how does it look standing alone?
