Hi MF,
Santa Ana Couch is also hardy and self regenerating as is Kikuyu, so what's your point ?
Plants prefer to be cut than torn, its less traumatic to them so I don't see your last point between Rotaries and cylinder. My main point was that Cylinder mowers are just not suitable for manicured lawns, but I will agree that they are now the preferred weapon of choice in better finishes.
Cheers,
BB.
