nonopr's experience seems right on. I weight 79kg and have an 08 111. For me, the 111 is a little big (rough ride in the chop) when the wind approaches 20 knots. I use my 7.6 if the wind is 15 - 18 knots and my 6.6 if over 18.
For you, the 111 and a 7.0 should be fine in the 14-17 knot range if you have steady winds, but you may need a larger sail if under 14 knots (7.5 - 8.5 range). It's a bit of a close call determining which board is best for you. It pretty much depends on the other boards that you may have and how the 101 or 111 fit into the line up.
