RE: Replacing a 105L Hyper
Considering the review Ian gives of the 101, I think your reasoning is perfect.
I would add that at your weight the 7.6 would be more light wind oriented than at mine, making the 101 even more apt. Nevertheless, I think that I must have been sailing the S95 with a 34 fin and 7.6 in about 12 knots (almost no whitecaps) with ease and fun.
My orientation towards the 95/94 derives from my sailing spot providing 7.0-6.6 conditions more often than 7.6 conditions.
