i think it is better to user a more slalom oriented board to use maybe a real race 4,5 or 4,8 sails with cambers on it. Depends on your experience.
so i think the bigger board is a good choice cause i sonics feel much smaller than other boards. you surf it fully powered on the fin. acceleration and running throgh the lulls is better, when volume is not to less. So if you take the 50, and you have maybe 45kg or less, there is not much space for that. You should have constantly high winds, but where are they? it is always gusty, everwhere around the world. Also jibing could be quite difficult for you, especially in the races.
the only problem is your weigth, the straps are very much outboard. Maybe a professional tuner / shaper in your town can help you by adding a few more positions for footstraps on the isonic for you. Or you can try the original positions, maybe it is OK, . Use a seat harness, especially when you are lightweigth like you.

I started surfing in the summer of 2007.
I just won the Aruba Hi-Winds 2008 slalom and longdistance for the New Kids (on my old second/third hand Exocet 75).
I need some advise on a new board.
What would be better for me, an isonic 50 or a 76?
My sail is a 4.0 I would like to go to some more races next year.
Maybe Bonaire or Sto. Domingo.
Hope you can help me out. THANKS
