Ok, mine, which I believe is strung correctly, as it matches Fischer brochures for the model, is strung 16m x 21c. Mains skip #8 throat and #8 hoop. Crosses start at #6 throat or #8 hoop. Shared holes are #6, 7, and 9 throat and #9 hoop.
Sorry to say, I don’t have any other string length data or tension, but 60 pounds or less will probably be fine.
