There is a development for a subdivision behind my house, and lots of cleared land, so I took my Rat, Av3, and AvX3, all in Star plastic, out for some throws.
The Rat is a bit more shallow than the AvX3, and both are more shallow than the Av3. On throws into headwinds, the Rat and AvX3 held their own, but the Av3 turned over. Into tailwinds, all three flew well.
Thrown at full power, the Rat and AX3 went very straight and had a slight fade at the end. The A3 drifted a little right then barely faded back. On less than full power throws, and when trying to hit a target (newly installed cable box near the road), the Rat had more finishing fade than the other two, followed by the AX3, then the A3 with little fade at all. The Rat also showed surprisingly good glide on the lower power throws.
Distance wise, the Aviar3 falls short of the other two. The AviarX3 and Rat got pretty much the same distances, which surprised me that the AvX3 got more than I expected relative to the Rat.
I'll work more with the AvX3 and Rat, and see if they start showing any differences. As of now, they seem a bit redundant. The Rat may be the answer for those that might be seeking a shallow, more overstable version of the Stud.
