WASD and Mouselook. Absolutely no better combination.
Basically, it's like this: W = forward, S = backward, A = strafe left, D = strafe right. Left mouse button to jump, right mouse button to throw rings, thumb button to spin. Make sure Mouse and Mouselook are turned on, and that Mousemove is turned off.
This is a standard control scheme that is used in many FPS games. It may take time to get used to, but you'll love it once you do, trust me.
Why? Well, you can aim and turn very easily just by moving the mouse. You can sidestep while turning, allowing you to gain greater control of your movement. You can move yourself into a gap or other opening, or position yourself precisely without having to rotate your character. And etc. etc...
