It seems to me that shifting the seat forward and back is functionally the same as adjusting the tilt of the seat.

@Nurse Ben

You are not moving the seat forward and backward in an arc centered on the spindle, but forward relative to the centerline of the unicycle. Think of the seat like you would think of a hammer, the seat is the head, so if you were to slide the seat/head forward on the post/handle, it changes the balance.

Moving the seat forward is no different than sitting forward or backward on the seat. I find that with the flat seat I am sitting forward as much as an inch more than I did on a curved seat. Tilting the seat helps keep me back, but only because it become more uncomfortable to get forward. Since the point of a flat seat is comfort, like Tim said, too much tilt defeats the purpose.

I agree with uniShark. You get exactly the same effect by tilting the saddle as by shifting the seat forwards and backwards. I’m not at all surprised that Ben prefers a saddle which is slightly tilted up, as that has the same effect as shifting the saddle forwards. Nor am I surprised than Ken prefers a slightly tilted down saddle - looking at the pictures he’s posted it is clear he likes a more rearwards saddle position.

Here are some diagrams to illustrate the point:
flat saddle
saddle moved forwards
extra bit of frame added in red
original black frame removed
unicycle rotated back so frame is upright

As you can see, if you tilt the saddle back and then rotate the frame forwards, what you get is a flat saddle shifted forwards (note that you’ll also want to increase your saddle height slightly). Who cares what angle the frame is at - a point illustrated by my second diagram of a frame type popular with cheap unicycles - what angle is the frame in that?
