H Viking, for your weight and the 9.0 most definitely the Falcon 140 or the Falcon LW - the 140 is the light wind machine that Pierre Mortefon and other Fanatic riders used to win multiple World Cups and works great with 9.0, 8.4 and ok with 7.7 too, has excellent range.
The 130 is ok with a 8.4, 9.0 is a bit too big and generally the 130 works well for lighter riders or our lady racers like Vice World Champion Marion Mortefon etc, who are not riding the very big sails.
The Light wind Falcon is slightly easier to use than the smaller 140, has smaller cutouts and has actually a pretty good top speed too - so if you need more light wind potential, then this could also be an option. Depends if you are doing races or not/how light exactly the wind is when you use your 9.0...for recreational sailing and the lowest/best light wind range, then the Falcon LW..for normal 9.0 sailing and racing, the Falcon 140...the Falcon LW is also a very good foil board to learn on, in case you decide to take that up later?
