I saw on Howe power steering's website that there is a joystick for rear steer axles, and was wonder if
A> has anyone ever used one of these in place of a front steering wheel?

(I kind of envisioned some dirt bike handle bars with tabs to move the joystick back and forth and some "stops" to keep the handlebars from pushing the joystick too far)

B> is the joystick "quick" enough to steer a front axle normally (off road only) or is that dependent on the size and output of the pump?
