Dave,
That's a solid change/enhancement - One of the few complaints a golfer could have had about DF was that below the hole tended to be the right/safe play almost all of the time. The intro of false fronts and expansion of greens to present new sections or pinnable areas is a great edition.
Have you noticed a change in potential for scoring? Up or down?
Generally, I thought DF was the most challenging course in the valley from about 6,700 yards. The general consensus was that it was tough off the tee (which is fair but often exaggerated) , it was really the ability to score into and around the greens that presented the most difficulty IMO - pre-reno.
What do you think?
