i would think 2 would be better than one that is packed. if you've got the room, i'd add another 1". just for future stuff.
something else you might want to consider, adding 2 pieces of 3" on the outside of the stringers, below the deck and using them as freshwater storage tanks. i have 2 6' pieces on either side of mine, below the rodboxes and it gives me 5 or 6 gallons of fresh water. i plumbed them to a pump located in the center of the hull, by the transom.
