Tain, The Glen, Troon, Shiskine, Murcar, Glasgow Gailes, Golspie, Troon Portland, Stonehaven - haven't played these, so can't comment
Carnoustie - too tough and expensive - I disagree. I really enjoyed Carnoustie, despite playing it on a miserable day and look forward to going back
Gullane 2 & 3 - though I could see myself changing my mind on these two, their proximity to other very fine courses seals their doom for now - again I disagree. I'd play these ahead of No 1 (and certainly when considering value) which I do think is over-rated. Yes, there's lots of good golf around there but Gullane 2 & 3 are both exactly the sort of course I would have thought you would enjoy.
Leven - not bad, but too many other courses nearby I would rather play given how rarely I make it up there - I played this for the first time this summer (with Ulrich) and loved it. Plenty of quirk, massive, undulating greens, I really enjoyed it and will certainly play it again next year. Also I have a soft spot for courses (Seaton Carew) that have less than promising backdrops and Leven, with its rather drab approach, entertainment arcade and caravan park satisfies that.
Crail - see above - despite being a member I have some sympathy here. Certainly I originally considered Crail a substitute for Elie. However, there's nothing quite as life-affirming as coming over the hill on a clear, sunny day and, as I have played it more I have come to appreciate it more. There are a number of good holes if no really great ones and the whole thing is a fun package.
