I played the old Dukes an awful lot when the company I worked for had a corporate membership. There was a lot of holes I really liked although its not much of a walking course. I've only walked the new Dukes and not fussed about the change from revetted to hairy lip style bunkering and don't know if any of the new green designs are really that better but it certainly looks a better routing now that they have the new ground at the bottom. In fairness to Peter Thomson, I don't think they had that option.

I think Mr Thomsons course, played and felt more Scottish, than what Mr Liddy has given us.
