I think this is an outdated, or just plain wrong, analysis. The new ryegrasses of today can be cut as low or lower than bent, are very easy to establish, and can easily be prepared for "fast and firm". My experiences with bluegrass, however, is that they are never cute quite as low, are more "puffy" and provide for inconsistent bounces on occasion. I do think bent is a great fairway surface unless you are growing it in a region that requires lots of watering, which creates the mushy stuff none of us want to see. My personal preference, among all grasses, would be bent and rye as co #1's, with bermuda(tifway II/419) and bluegrass pretty far behind...
