I have the F93 and sail it with a 6.7 RSR & are 85kg. This is a great combo, infact I am considering getting a 6.2 instead. Have done 34+ knots with this combo.
I would go for the 101, to sail with 6.2 and 7.2. No doubts. The boards get up and going very quick for thier volume, its more a function of width. The control is outstanding.
I would reccomend getting some good slalom fins, as the supplied fin wont work with the RS6.
