What? The 6-footer never got used again after season 1 until BOBW and Generations? Really?
Not quite. The 6-footer was used throughout season 2 and early season 3. The 4-foot miniature was introduced in season 3's "The Defector," and after that the 6-footer was only hauled out when they needed new footage of the ship in separated mode, which was basically just BOBW and GEN, yes.
