I tried a Caiman on the course for the first time today. Champion, 175g. Given the name of the disc, the comparisons to the Gator are obvious. Gator is listed at 5, 2, 0, 3, while the Caiman is listed at 5.5, 2, 0, 4. Based on what I saw today, I agree with the numbers for the Caiman.
The Caiman seems slightly faster than the Gator despite having the same rim width and depth. There is a bead on the Caiman, but it's smaller than that on the Gator. Caiman has a very slight dome. My 1 Gator is flat to the point of being concave.
Honestly, the Caiman reminds me of a Zone, but slightly smaller diameter. It has a fairly clunky, glideless flight. No matter how hard I hammered on the Caiman it didn't seem to respond well with remarkable distance. This thing seems to fall out of the air like a rock when it starts losing momentum. I like the hand feel on the Caiman as well. The bead is barely detectable.
On the course, I was using the Caiman and Zone for the same shots.... and getting almost the same results. The Caiman was shorter and more overstable than the (Get Freaky) FLX Z Zone I had it against today. The Caiman works well on upshots or short tee shots where accuracy is a must. The disc lands softly and sticks. No ridiculous skips, bounces, or rollaways.
Top distance with the Caiman was probably 320'. I didn't really try to mash it out for max distance at any point. The Zone was flying further with less effort.
Conclusions: The Caiman seems to fly as the numbers say. This is a good disc for short, accurate drives or upshots. The Caiman is very predictably overstable, and has a hard late fade. Glide is minimal, and this disc won't get pushed around much by wind. My only real gripe about the Caiman is that it can't be pushed hard for any extra distance. On some shots I felt like I smashed this thing only to have it land stubbornly short. The Caiman might be the lowest gliding midrange I've ever thrown. I get better distance out of the Gator than the Caiman. The Gator fades later and less harshly. IMO, the only noteworthy difference between the Caiman and Gator is that the Caiman has a much smaller bead. Caiman is definitely not a disc for new players or noodle arms. This seems like a disc for very specific shotmaking.
I recommend the Caiman. I liked everything it did today, and I was getting it close to the basket easily on short par 3's. That said, It isn't going to boot the Zone out of my bag.
