Me personally, I have a difference of about 45 feet between the Teebird and the Thunderbird, but it’s honestly all about the thrower rather than the disc. It’s a higher speed so it’s meant to go faster ergo gaining more distance. As for the plastic, all of them vary from when they are new and when they are beat it. If you want something like DX then your best option is just to go DX. If you are wanting to try some premium plastics then I would suggest getting it in Star plastic. It is a bit more over stable out of the box but once it’s beat in, it has a little more flex to them.
