I'm in South Texas, and my course redid the greens last year with Champion. We did not have to overseed in the winter as we normally do, so the course was more playable year round. There has been a lot more ongoing maintenance than with the previous Bermuda; aeration, sanding, light verticutting, etc. But nothing that takes the greens out of play. When they're in good shape, our super is able to cut them down and get them really quick, something that was harder to do with the Bermuda. From killing the old greens to playing on the new greens was about 9 - 10 weeks last summer/fall.
