Twin Stick control alternative with keyboard & mouse

[Cero]

twin stick games are kinda fun, since you can move an shoot independently.
I'm thinking of games like Smash TV, Robotron 2084 and maybe Geometry Wars to name a newer example.

So when making a game for PC with keyboard and mouse, what control scheme do you think works best to replicate this experience ?

I would go with keyboard movement and turning/aiming in the direction of the mouse curser.

WASD for forward, back, and strafing

and Mouse for changing direction and shooting

that's how most games do it
