This greatly depends on what you want with the board.
I use the Atom 110 for comfort-speedsurfing:
Front and back footstrap in outer row
Front footstrap in screw most behind
Back footstrap in screw second from behind
Fin is good for allround freeriding etc and will work with your sailsizes.
If you want to surf fast in a straight line the fin is to soft and a stiffer, more stable fin will work better I guess.
