Throwing Thought: the Windup
Bring the disc back as far as you can as soon as you can.
As you pivot, or as you stand trapped on the sideline looking for an open cut to throw to, don’t think about just getting the disc over to your forehand or backhand side–think also about getting the disc (your arm) to the point from which you only have to move forward to throw.
In other words, seek to eliminate the windup from your throw–who do you think is more likely to be point-blocked or forced to adjusting their throw last-second: the girl who puts her head down, steps out, winds up, and releases, or the girl whose step, wind-up, and release are one fluid motion? Don’t allow your body to hesitate.
As you pivot over to your backhand side, take the step one step (pun intended) farther by torquing your body before your foot hits the ground. Thusly coiled, all you have to do is pull the trigger if the throw is there–no second is wasted on the gap between evaluation and execution (assuming you can wind up and look upfield to evaluate at the same time, which you damn well better be able to). Similarly with a forehand, aim to land from your step with the disc already coming back into your windup so that all your motion explodes forward upon touchdown.
If you are always preparing your body to throw, your pivot is always a threat and every fake must be respected. Developing a repertoire of convincing, effective fakes will follow naturally if you work to make your pivot, windup, and release more efficient.
EDIT: Likely also inspired by the huddle, Muffin offers his take on throwing for distance. He articulates the nuance of the shoulder load (he calls it the shoulder jerk) a bit better than I do.
