Bob,
Sorry for the late reply; just got back in town after two weeks away from the computer.
Your club might want to check with Trophy Club in Alpharetta. They put in Champion last year, and have now been through a winter. They did not paint, and I saw a cover adjacent to the first green as I drove by during the winter months. I have no idea whether they had to use the covers or not.
Though I've played a number of rounds on Champion, I haven't played the new greens at Trophy. But friends who have give good reports.
