XGD has been a game changer at our club in Cleveland, Ohio, where it’s all clay soils. It is amazing how quickly our greens drain with that system in place. About the only complaint now is that the greens firm up much faster than the fairways so the overall presentation of the course can be mis-matched in the first couple of days after a heavy rainfall. We have installed it in a couple of our approaches as well to help with several holes where the architect’s strategy was to encourage a run up shot.
