Thanks everyone, more responses than I was expecting so sorry if I dont respond to everyone directly. However a couple of things jump out.
Brian,
You are probably correct in that the examples I've given were all played some time ago, and so its fair to say my understanding and experience of golf course architecture wasnt as developed or refined as it is now. This reminds me that Sean Arble will often when posting lists reference courses left off said list as its been a while since he played there. This is a combination of factors I suppose, developing tastes and understanding as well as fading memory
but is probably a valid point the next time one starts praising or criticising a course played only once a long time ago...
Talking of Sean, interesting point about the number of people you play with? On one play getting to see how 3 others get on must certainly help add to the mix of understanding? I know a few courses I've played once on my own where I certainly didnt get as good an understanding as if there had been several others to observe? I also know a few courses I've played once were I had plenty of time and spent more time looking at different angles, checking out features etc than playing the actual game?
Its tricky, we all certainly have different abilities and talents when it comes to observations. This in turn will have an impact on how we would rate or like a course. As Tom Kelly says, I'm certainly finding I keep positive (but negative also) opinions in check a little more on only one play these days, and I'm also starting to add the caveat and make it clear if expressing an opinion on a course if I've only really got the one days experience behind me.
Lastly, I know my list of favourite courses is heavily populated by courses I've played a reasonable amount but whether I've played them more because i like them or I like them because I've played them more, I could say.
Cheers,
James
