With your weight and sails, I recomand you the iSonic 144 who plane earlier than the Carve 162 and the Futura 155. This board was develop specialy for racers who are heavy, for the lighter one you have the iSonic 133. Personaly I am using SL2 52cm with my Code Red 10mē in slalom, but I have also a Formula for lighter winds.
In you don't do any competition, you can choose also the iSonic 150 who will be good to replace your Formula, in this case your R13 will be perfect for this board.
All the best
