That a course in South Carolina is switching to bent answers the question. The director of maintenance (I am sure he has a more impressive title) at a premier 36-hole golf facility in coastal SE told me that if given the choice, he would maintain bent greens at his club as opposed to the new dwarf bermudas he was responsible for. Not only were the dwarf bermudas (Tiff-Eagle, I believe) very labor intensive to maintain at good speeds with minimal grain, they had to fight the transition periods twice a year and the greens were in "like-bent" conditions for only a very short time.
In the D/FW area, those courses positioning themselves as "quality" have bent grass greens. Colonial CC, probably the first course in this part of the country to use bent, refuses to switch despite having redone their greens several times. Because of its river-bottom location and huge trees, it is a prime candidate for a hardier grass, but a switch to bermuda is very unlikely to happen.
My home course has Champions bermuda on the greens and a lot of people rave about it. The greens look good, but they putt more like recently aereated bent. You can hit three putts with similar strokes from the same spot 10' away, and the ball can do three different things. For those who find this interesting and challenging, my hat is off to you. A sure way to ruin a perfectly fluid and rythmic putting stroke is to spend some time on bermuda greens.
From the standpoint of fairways, that is another story. Like Bob, I too have played on firm common bermuda where the ball runs a long ways. Watch #11 at the Colonial NIT when the course does not get a lot of rain and you'll see 50 yards of run (bermuda 419 fairways). The softness may have a little to do with the thickness and strength of the grass, but over-watering is the biggest culprit. In fact, one of the reasons many of our SW courses have such wet entries is that superintendents over-water the greens in order to make them more receptive. The water has to run some place, with surface drainage often designed to the front of the greens.
