Tuss, the GD system, as I was taught it (by some guys named Davis and Ehret) advocates an aggressive slot position which means that you might seem a bit exposed at times. The upside of this is that you will always have a good, clear view of the outside corner and low pitches. If you creep back toward the catcher and get too low, the catcher is probably blocking your view of the outside corner and low pitch.

It is my personal opinion that you are never adequately locked in using just one hand/arm to lock. That's just my opinion, your mileage may vary. The GD system does not advocate a heel/toe relationship nor the wrapping of an arm in front of your stomach. The key to making the GD work is to be balanced and solid in your stance, consistent in your head height for a pitch to pitch view that never varies between batters, and relaxed so that you can use your eyes properly.
