The cross pollenation argument aside, there are other reasons as well.
There are quite a few club fields across the country that are not "turbine friendly" any more or never were. Also, some fields have to shut down turbine operations during the summer, during times of high fire danger .
EDF's fill the void at these sites. A good, fast EDF should be in everyones stable. I for one will have one soon.
