Pros:
Timmons is a super fun and somewhat easy course with a variety of wooded holes that will test your control while still giving you chances to air it out once in a while. The design of the course allows you to have aggressive and conservative shots on nearly every hole and will punish shots that go off the fairway, namely, with the creek. But don't let the water hazards scare you; discs can be retrieved from nearly everywhere if you're willing to poke with a stick or get a shoe wet.
Every kind of shot will be able to stand out here. The few long holes will help the bombers. Some holes curve right or left, and most can be reached with a few different lines. Some holes favor overhand, with a steep upslope on two holes and many holes where absolute precision is required. Holes 2 and 14 favor putter drives, and most are about right for a midrange.
Death putts are super common here. With the creek lurking near the basket on half of the front nine, and other baskets on a sideslope (8, 10, 16), and drop-offs if you go long, putting is put at a premium. Furthermore, because of the shapes of many fairways, it's difficult to be parked off the tee. You may run into the foliage late near the basket, or get to the top of a hill but are left short, with a dangerous putt for birdie or par.
Open and wooded holes are mixed excellently. Every hole has some danger to get into, but the difficulty of the tee shot and the number of trees you could hit early varies significantly. Holes 11, 13, 15, and 18 are the more open holes, but they all have danger in either woods, hills, or the creek. I especially like 18 as a finishing hole, though it will be a tweener for many players. The more wooded ones are still fair, providing clear lines that anyone should be able to hit but will be more difficult the more aggressive your drive is.
A few holes favor anhyzer shots, regardless of how you throw. Holes 8, 9, 13, and 16 may be good for this, and while they all offer hyzer lines for some players, many will be throwing anhyzer. Hole 10 has an interesting high route and left route, both of which could have anhyzer shots thrown on them. This all is an indication of good course design.
There are also a lot of ace run holes. Some are rather dangerous if you run it (2, 17), but some are a little safer (4, 15).
Cons:
In all honesty, it's a rather easy course. Most of the holes under 300 feet won't provide a ton of challenge for top players, and even if you don't know your way around the course, you may find yourself with a lot of birdies. Now, it may seem like this is a good course for beginners, but there are enough trees and holes with the creek in play that this isn't quite the case. As a result, the number of people for whom this is an excellent course is quite low. That said, I think anyone should be able to enjoy themselves here at least a little.
A few holes really only favor one kind of shot. Hole 12 is the worst offender, with RHBH/LHFH being the only legit option, and hole 4 isn't much better. Overall, I think this course favors the RHBH player a little too much. There are exceptions, of course (holes 4 and 5), but that's about it.
There are no alternate pins, something that would make this course much better. I would like to see some short pins on some of the harder holes, namely 5 and 18, as well as a right pin on 12. Hole 16 has plenty of room to spread out, and if you really tried hard, you could squeeze in alternate pins on 8 and 14. Because this course is a little on the short side, I can imagine it getting repetitive after a while when every tee shot is the same. There's also the hillside between holes 16 and 9 that wasn't utilized, though it's not a grassy area and erosion could have been an issue if the course ran through there.
No par 4's. Hole 5 could be considered one, and there isn't a whole lot of room for longer holes, but it is something the course lacks that's preventing it from getting to the next level.
Other Thoughts:
This course certainly isn't the best imaginable, but it's still a fun play, and the pros far outweigh the cons. But the lack of variety and difficulty for top players prevent me from giving a high rating, though if some work is put in here, I can see a 4.0 rating being on the horizon.
A few tee signs are damaged or missing, but it's not a big deal since navigation is mostly straightforward and you should be able to see the basket from the tee. The only spot of tricky navigation is hole 12, which is across the road and might be easy to skip, since the tee of 13 is near the basket of 11.
Mud could potentially be an issue, but I can't say for certain. There is a mini creek on the fairway of 11, though. But as far as I can tell, the creek swallows up the water pretty well.
