Philip/Tom,
I have played both on one day - it is an exceedingly good 36 hole facility (with the usual excellent French lunch in between). I preferred Golf du Medoc the Bill Coore course which was the best of several very good courses we played in that region of France (Hossegor and Chiberta near Biarritz are also very good). However since we played Rod's course as a second eighteen and after a good lunch and a nice bottle of Red Wine our judgement may have been clouded! We were considering returning to play next Autumn as Ireland are playing one match in the rugby world cup in Bordeaux
Regards, Johnny
