"I don't mind the new hillside assuming it is more functional for golfers."
It may be more "functional" or easier. But it wasn't a good idea on great historic course like Toronto where challenge and a natural aesthetic are important. I guess the 6th at Royal Dornoch could be made more functional with a few terraces added to its banks.
Anyway moving on. I played the 6th green at Burnham before Hawtree worked on it but I don't really remember it. I did play the current 6th soon after it was redone, I thought it was on the severe side and I'm not sure about the surrounding mounding: not the best but not terrible, it's a bit uniform.
Hawtree occasionally adds a mounding complex. See the 18th at Carnoustie and 18th on Sunn New. So I wonder if this has any bearing on the mounding to be added on TOC
Also does anyone know in detail what Hawtree and the R&A did at Muirfield? All I heard was that some bunkers were brought in closer to the greens. But I suspect some mounds may have been added to green surrounds (6th?).
