Here are the modifications I would think about to try and reward the player who can hit a long accurate drive. Many of these might not work on the ground as unfortunately my memory of the terrain has faded somewhat in the last 6 years:
2. Remove some trees and add a tee far enough back that the bunker in the middle of the fairway matters (maybe 50 extra yards)
7. Put a tee back into 9W fairway that could get some use by the members as a forward tee on 9W - (50 yards)
10. This would be controversial but what about putting a tee to the right of 9 green, creating a crossover but bringing the diagonal bunker more into play. The drive would be blind, but would return the hole to being a very stout long challenge. 50 yards
12. Use the tee for 9W (maybe 50 yards) - would create another crossover.
14 - use the other par three that is being skipped now
15 - use one of the forward left tees on the hole that is being used as the 14th now and remove the trees in the way (100 yards)
Here is a link to the aerial I reviewed in thinking about this
