Why not consider Maui Sails TR race sails. I have been using them for years and have always had 3-5 cam race sails from 6.6 on up to 11.0 for the last 15-20 years.
I like the range, stability and speed, especially with adjustable outhauls. At your size, the extra weight of these sails should not be a problem. I weigh 78 kg and can manage them quite well.
The TR-6 sails from 11.0 up have 5 cams and 8.4 down have 4.
Another options is the Titan, the next step down from the TR sails with fewer cams, a standard luff sleeve, lighter weight and less money.
Speed is achieved with maximum control and that's where you need sails that have a wide power range and can be managed when overpowered.
