tips for my new board welcome!

Hello People,

a friend of mine just asked me to make him a new board.He was thinking about  a 6'4''x 20''x 2 3/4''.He wants a board that goes fast on small or weak waves (and he's not a pro....but he definately wants a shortboard.).He's about 187 cm tall and weights about 85 kg.What i wanted to ask to all you sway's friends is if you had a good template to pass me and some tips about concaves.Should it be a thruster or a quad?And the last thing is the glassing: he wants the board purple for 2/5 of the board on the nose and for 3/5 green...do you have any pictures of boards made like that?( he wants pigments only).

Many many thanks
