I have one, but I have nothing of substance to add. It's too fast for me to really tell what it's supposed to do. The plastic is nice, though.
*adds something after he says he has nothing to add*
I'm planning on adding a "this is too fast for me but everybody else is doing it so what the Hell" driver to my bag. The Tern and Krait are early leaders for that slot. The Krait is more comfortable in the hand and they fly exactly the same for me (because I have no business throwing either one) so I'll probably go with the Krait. The Tern does seem to fly farther for me than some other high-speed discs I've tried like the Vulcan and the Archon, and it doesn't seem to dump as badly as a Boss as it slows down.
If you have any other questions about how discs I can't throw fly for me, I'll be here all week.
