    a deck;

    a longitudinal slot defined in said deck;

    a longitudinal row of staple cavities; and

    a base;

    staples removably stored in said longitudinal row of staple cavities;

    a longitudinal row of staple drivers movable between an unfired position and a fired position to drive said staples toward the anvil; and

    a firing system movable toward said distal end during a staple firing stroke to sequentially move said staple drivers between said unfired position and said fired position, wherein said longitudinal row of staple drivers comprises;

    a first staple driver comprising a first bottom drive surface configured to be driven by said firing system and a first support surface configured to drive a first said staple toward the anvil, wherein a first driver distance is defined between said first bottom drive surface and said first support surface, and wherein said first bottom drive surface is positioned a first support height distance from said base; and

    a second staple driver comprising a second bottom drive surface configured to be driven by said firing system and a second support surface configured to drive a second said staple toward the anvil, wherein a second driver distance is defined between said second bottom drive surface and said second support surface, wherein said second driver distance is different than said first driver distance, wherein said second bottom drive surface is positioned a second support height distance from said base, and wherein said first support height distance is different than said second support height distance prior to said staple firing stroke.
