Def get your weight in the front. I run a 600 pound sac in the walk through + 300 pounds of water/sand/lead under the bowseats & chain locker. In the back I have two 500 pound sacs either side of the motor but I only fill them right up if there is only the driver in the boat. With 4-6 peeps in the boat the back sacs might be 1/2 fill or less.
