Due to the inspiration of this thread, I finally got a Thunderbird (Pro plastic) and compared it against the Vulture (Titanium) and Getaway (Fuzion Burst).
While they all flew reasonably well and similar, the combination of different variables left me with a more positive overall impression of the Thunderbird. The variables:
1. Rim. The rim is more comfortable than the Vulture and smaller than the Getaway. It is a good median between the two.
2. Distance. While the plastics were different and can account for some variances in distance, I was out driving the other two with the Thunderbird. Even if I had the comparable plastic in the Thunderbird, I don't think the distances would have been too different.
3. Plastics. With the point above, the Thunderbird comes in a bunch of different plastics which can afford me different lines and distances.
4. Weights. I like the fact it covers a wide spectrum of weights.
5. Colors. Multiple colors available. As well, I like to dye discs and white seems to be easier to find.
6. Availability. They are going to be easier to find, whether in mom-and-pops, chain store, trading, or tournaments.
7. Longevity. Due to it's success, I don't have to worry about going extinct.
with that said, I am going to bench the other two and roll with the Thunderbird.
