I am not on Starboards but are of similar size. In S-board range I would choose something around 115 l (or maybe 125 if wind tend to be more 20 than 25 knots). As a 2 board solution I think that 133 and 111, or even 125 and 101 would suit you good. Myself I ride 128 L (76 cm wide), appr 105 L (65 wide) , 95 L (59 wide) and soon a 80 l (56 wide) to cover everythin from 10-12 knots and upwards. Sails range from 9,0-6,0 Race sails. I hope that this helps a bit. I am sure that S-board guys can fill you in with more details regarding specific starboard-boards.
