Sexton Firebirds just so happen to be made from my favorite plastic. Color glow is so grippy, gummy, glidey, and durable all at the same time. I think other discs fly the same, but other discs aren't made from color glow.
I did however snag some color glow non sexton firebirds, and they're the same thing just with different stamp. Legacy had some anniversary Enemies made of their own color glow as well, and they're even gummier! Can't wait to break those out.
I also use Barela Teebird3s, FD3, Leopard3, and even Wraiths in color glow. I would totally use color glow MD3s in place of my Buzzzes, but the prices on those, well....
