I'm working in clay topsoil. There is a Round-Up resistant species of sheep's fescue (Festuca ovina) called "Arurora Gold". Once established, this fescue will tolerate, to a certain extent, light doses of Round-Up (glyphosate) that will eliminate pretty much everything else. It's resistant, but a full rate will burn it good, so you need to be careful and apply 1/4 to 1/2 rates and repeat application a few weeks apart. And don't try anything until the fescue is mature.
The Aurora Gold will grow thick in fertile soils, and will still swallow balls, but you can achieve a more uniform, lower growing cover that gives the golfer more of a chance and is an improvement over a general mix of species.
