I tried this disc in GStar plastic (the only plastic this disc is made in, for the time being) at 180 grams.
Pertaining to the physical properties of this disc, the biggest difference between this disc and almost every other disc that you've thrown is the VTech (convex) wing configuration. Initially the VTech rim feels a little odd in your hand, but I would mainly attribute that to the fact that I had never thrown anything with a true convex wing shape before; and honestly, you don't notice it while you're throwing. Another thing that is a little different is the bead on this disc, which I think is thicker than the beads on a Roc, or even a Gator. Although I am used to throwing discs with larger beads, it does make the disc itself feel quite substantial, which could be problematic for people who aren't used to throwing discs with a decent sized bead (which is typically newer players), as well as people who have smaller hands.
The flight of the disc itself is very close to what it is rated at; it is about as fast as every other speed 5 disc I've thrown, it has some high speed turn, and almost no low speed fade. The only thing is that I wouldn't consider this disc to have as much glide as advertised; to me the amount of glide this disc has is about the same as a decently seasoned Rancho Roc (4). I will say that I am a huge fan of the VTech style rim for the fact that even when thrown with a lot of snap and into a decent headwind the Wombat did not turn more than I expected it to; which usually isn't the case for discs that have any degree of high speed turn. Although after throwing a VRoc, I think the VTech rim is what is causing the glide of these VTech discs to not quite measure up, and this really impacts the range in which you can achieve.
Although I am a fan of how the VTech style wing limits the amount of high speed turn that the disc has, the Wombat won't be finding it's way into my bag. Simply put, the high speed turn is too much to use this disc as a strait flying mid, and not quite enough to use this as a turnover mid for me. I would think this disc would be amazing for newer players with slower arm speed who are looking for a wind fighting/approach mid though, due to the resistance this disc has to turn too much, as well as it's not too glidey nature, but I could see the large bead and fairly large feel of the rim of the Wombat making it considerably less appealing to newer players, and players with smaller hands.
