A.G.-
Many times. I was a member of a club that converted from SR1020 (bent) to Champion and stopped over-seeding after the first year. It is my favorite bermuda hybrid. In fact, the only time I have ever played bermuda greens that putted close to well-maintained bent was at Whispering Pines. They had converted to Champion a couple of years before, and it was at the end of a drought. The greens were smooth, ultra-fast, and extremely firm. Unfortunately, two guys in our foursome were mid-handicappers and just couldn't control the spin on their chips and pitches so it was a very long day for them.
I am probably the exception, but I prefer putting up with pins on the edges and soft, bumpy conditions in the summer with bent than having the new hybrid bermuda greens which are put in to save on maintenance costs. At least in the north Texas area, unless the club is willing to spend for very frequent verti-cutting, grooming, rolling, hand watering, etc. to minimize the grain, I don't think that Champion can match the performance of bent.
