I have a '75 000-28 strung with lights (D'Addario EJ16). These strings work best for me; on my 000-28 and my OM-21. I tried mediums on my OM but they were too much to handle. The 000s have straight (the OM has scalloped) and slightly thicker braces than OMs so I don't think I would have problems. But, please don't call me if your guitar implodes.
