A lot depends on the typical conditions you normally encounter as Mark h says. My favorite sails with my iS 111 are 6.6 and 7.6, so the 111 fits your two smaller sails. I weight 78kg.
Your the 8.0 and 9.0 sails work best with the 133, so that's where nonopr is coming from.
If you have windy conditions and will be looking for smaller sails ( 5.8 & 5.0), then the 101 and 133 may be the answer. However, the 101 may be a little big in 5.0 wind.
No easy answer here.
