Pat,
I do have the "home bias" on my side since a Cupp is my "home course", although I am in no way related to Mr Cupp or his organization.
I realize that Cupp bashing is the current favorite thing to do on many websites and blogs but based on how "professionals" performed on the greens at Ghost Creek over the past w/e I would have to say that there is more to them than many would suggest.
Again, at the Safeway Classic, I saw the ladies continually misreading putts on the greens from 5+ feet away. I am not suggesting that anyone would miss a 7 foot but by 4+ inches, I am merely suggesting that Cupp greens can be sneaky and difficult to read due to subtle contours around the hole that cause a ball to move more or less than you would suspect depending on the situation.
Suzann Petterson missed a 6 footer to win, Redman missed a 3 footer to make the second hole of the playoff, I saw the ladies missing numerous short distance putts over three days at the 7th green which can be very challenging to putt.
I have never played LN so I have no idea what the deal is at 18, but if the greens there are like the ones at Ghost then they can certainly be sneaky due to subtlety.
I know I have a much easier time reading and dropping putts while playing other parkland courses where greens tend to slope in one direction and the reads into pinnable areas tend to have less subtle movement and/or noise that creates confusion.
