Bill McBride,
I don't mean to hijack Tony's thread, but I think that Champion might be getting a bad rap, though varying soil and climate conditions as much as budget may have something to do with it. Great Southwest Golf Club between Dallas and Fort Worth converted its Brauer designed bent (SR1020) greens to Champion some 8+ years ago and they are among the best bermuda surfaces in this part of the country. It is a low-budget operation, probably around $500,000 annually, and other than two deep tyne and two smaller aerations each year plus some light sanding, they don't do much more to them. They don't seem to verticut frequently, and to the best of my knowledge, they don't roll, brush, or groom them with any regularity. Not surprisingly, the members are generally happy with the greens, but complain about how often they're punched and top-dressed.
The biggest complaints I've heard about Champion in this part of the country is that they can get pretty firm and fast, that they are hard to overseed without really tearing up the dense canopy (to get the seed to the soil), and that water tends to run-off a bit fast requiring heavier irrigation for the high spots creating soft conditions elsewhere, particularly the approaches (most greens drain to the front around here). I've also heard some concern that Champion may not do well in cold conditions, so some transition areas may do better with a different hybrid.
Concerning Tiffdwarf, the greens at a local muni were rebuilt using this strain. Lower maintenance was the main reason for choosing it. Now that I've played the ultradwarfs including Miniverde for a number of years, there really is no comparison. Unfortunately for this course (and the superintendent who chose Tiffdwarf), the city's other more upscale course converted to Tiffeagle, and the muni players as well as a fairly prominent councilman who play both courses are demanding that they gas the Tiffdwarf and convert to Eagle. The architect who redid the course agreed with the initial choice of Tiffdwarf, but acknowledges that even this older, cheaper grass requires considerable maintenance. The bottom line is that you get what you pay for. If the golfers demand putting conditions approaching bent, the ultradwarfs is the way to go. From what I am told, we are talking about more ongoing expense, but as the Great Southwest experience suggests, it may not be a huge amount more.
