Define the question a little more. What do you mean by strike zone? Do you mean the location where it is easiest to hit the ball?
Most pros prefer to have a strike zone below shoulder level. That would even include Gasquet, as I've seen him hit a jumping 1hbh put-away on a high ball in order to drop the strike zone. Gasquet will tend to spin it if it gets too high.
