Tony,
Why are any of these changes necessary? On 11, it's not as if that bunker looks out of place, and if playability is the concern there are only about six others surrounding the green. The trees between 9 and 10 make zero sense. Part of the appeal of the 9th is the golfer has plenty of bailout room to steer him away from the short route to the left. I guess the loss of the back tee at the 10th does not matter too much. It probably gets little use anyways. However, the drive from the back tee is much more compelling than the one from the front.
It all makes little sense. Addington has minimal funds as it is, and they should not spend money on needless changes.
