Sean,
The grass types used on gourses int he deep south are much more heat tolerant now then before. Combine that with other advantages such as fans, pesticides, handwatering, more aerifying have allowed bentgrass to be located much further south that what it's ideal climate is. Mind you, Augusta has only had bentgrass for the last 25 years, and they can keep the greens alive partially cause they don't have to worry about golf in the summer cause they are closed. Bentgrass is a far superior putting surface than the ultradwafts and to me, it's worth the strain. If a golf course has to overseed and transition, the greens aren't going to be perfect 3 months out of the year anyways, just like bentgrass in the south. many more courses have bentgrass now because of the advances inthe last 25 years. Many of the mid range clubs, because of the time and effort that bentgrass does take, as switching back to an ultradwafts.
