Pros:
After the revamp and slight redesign, Circle C is the premiere Austin disc golf course and my personal favorite of any course I've ever played. There are so many pros it's going to be hard to list, but I'll give it a shot:
-Every hole has a concrete teepad, with most holes having dual concrete tees.
-On most holes, the difference between the long and short tee not only adds distance, but it adds a much more difficult line that needs to be hit.
-Limestone block-benches located at most teepads.
-Detailed teesign for every teepad.
-Mulch in the fairways, mulch around the baskets, rock drainage areas, and rock paths between holes keeps the mud situation after a rain quite manageable and makes this course the best in the area to play after recent rains.
-The diversity of this course is simply unmatched. Between uphill, downhill, tunnels, bombers, technical, right turning, left turning, 2 par 5s, and multiple par 4s, this course has it all. The only golf shot not found at this course is a wide open field shot like you see on many holes at Old Settler's or #16 at Pease.
-There is a field hockey/soccer field right next to the first tee that is usually unoccupied and great for warm-up drives. That's in addition to the two warm-up baskets that you'll find before the first tee.
-Everything is in excellent condition from the baskets to the tee pads to the trimmed limbs along the fairways to the branch sculptures to well...everything.
-Space-age trash cans every so often, but oddly some people still prefer to use the ground as their waste receptacle.
-Restrooms located right before the first tee.
-The difficulty level of this course is high, especially from the long tees. Every hole from the short 200 footers to the 900 foot bombers require accuracy and precision. Even on the long holes it is more important to have precision. Long-arms that are not accurate are going to be punished heavily on this course. Every shot actually requires you to think before you throw, especially considering the rough out here is usually quite difficult to shoot out of.
-The landscaping out here is really top notch. From the earlier mentioned rock walkways and drainage ditches to the terraced hills and erosion-preventing tee-pads that are bordered by cedar logs embedded in the ground and many other nuances separate this course from others in the area.
-For the most part this course flows well and it is never more evident then playing the course when it is crowded, which oddly doesn't happen as much as some other courses in town.
Cons:
I've been trying to think of a con for quite some time and I just can't come up with any. I've heard of people that complain about a few of the baskets not being regulation height, but I really don't see this as a "problem" or "con." On the uphill tunnel hole the basket is elevated above some double-terraced landscaping. For me, this actually adds to the overall intimidating feel of the hole as the basket looms high on the hill overlooking your measly attempt of landing on the green.
Another aspect of this course that may be considered a con are the jagged rocks near the basket and in the fairway of #7, but that would be like giving a con to mother nature and I just can't do that.
Honestly, I have no cons for this course, and this is the ONLY course that I can say that for.
Other Thoughts:
The only negative that I can think of is that my 2 favorite teeboxes are located on the same hole (#12).. I've played this course hundreds of times and every time I play it I actually end up liking it more. This is not the closest course to where I live, but I'm more than willing to drive a few extra miles to play a course of this caliber.
I've gotta give props to the location of the long teepad on #12. It is the absolute best teebox location of any hole I've ever played. It's up on this hill and there is a safe straight fairway that you can take, or for those willing to risk it, there's an amazing over-the-tree-tops line that you can take. The further right you aim, the closer to the pin you can possibly land, but the more trees that you have to shoot over. It is the definitive risk-reward type of shot because the level of risk scales with how big your balls are. Many a disc have been lost in those woods from people (myself included) not clearing the tree tops or cutting the disc too far right.
