Things I would like to see:
First and foremost a drainage system would be HUGE, when we played the course was practically under water, I guess if they get two days of rain in a row the course closes.
Second, actually mow some fairways, and have more short cut grass around the greens. You can see that there are all kinds of run offs and false fronts that should be in play, but it is just really tall grass everywhere. For example on the back on #15, the par 5. It is asking for short grass if you go long over the green with a slope leading down into the dry creek. There were areas like this all over the golf course.
Third, put a little nicer sand in the bunkers, the sand at Kings Links another Aberdeen City Council course was much nicer than that at Hazlehead.
Fourth, I know this sounds odd but they have like 4' flags there, it is very odd. Get some nice normal length flags.
The last two aren't really needed but would be nice.
If they took care of these simple things, this course would be a hidden gem.
Just my opinion.
