Since I am a member of a club at a resort, we have no say on maintenance, but I have questions. How often is the rough mowed? How often is the grass around the greens mowed? For me, length of rough completely changes a course and should be altered based on the playability of the rough and the hardness/softness of greens and wind conditions. Simply, long rough makes some courses just monsters. (Played Pinehurst #2 a few days before they closed it in preparattion for the Open a few years back. Yikes). And the recovery from around the greens when rough is too long can make it very difficult. Would the members notice if the rough was cut to 2.5" instead of 3" or whatever your "normal" is? What about you incrementally take it down so they don't notice? Because if you slowly lowered it over a year or two, if you took it back to the prior "normal" they would probably scream that it is too long.
