If a disc is at / angle it is turning left (rhbh). A firebird is going to keep / angle and dive to the ground. A valk if thrown properly is going to level out while turning left, then as it stalls turns left even more as long as it doesn't level out past -- angle.

This throw requires some touch/finese, but with practice everybody can do it and it will improve your entire game more than you think.

Hope that clears some stuff up for somebody.
