Our team has gone through a few joystick options, but we've settled on double joysticks.
We have one joystick that has X/Y axes used for strafing, and second 3d joystick where we only use the Z axis (for rotation).
Xbox controller comes in second-- X/Y on the left for strafing, and X on the right for rotation
As for a single 3d joystick, I find it really hard to control

That double joystick layout you have looks pretty interesting... maybe I'll test it out myself.
However, I think it might be rather difficult to control the rotation like that, but I can't think of any better double X/Y layouts.
