There is also the fact that the plane's vertical CG is above the main gear wheels. So when you lower the tail, the plane rotates around the axis of the wheels. That effectively shifts the plane's horizontal CG backwards relative to the main gear wheels. The taller your main gear and the shorter your tail wheel are, the more pronounced the effect is. If you don't believe me, stack a few books and set your main wheels on them. See how much weight you feel in the tail with the nose up like that versus how heavy it feels when you hold the tail in flight position as it would be just prior to takeoff.
