I prefer 2 up front. seems like it makes more of difference in shallower water since the boat is more prone to spook shallow fish. that being said, it'll work ok front and back. give him some rod holders on both sides and some long rods so he can put out a good spread and he'll catch fish off the back if you fish shallow water. if you fish deeper water I don't think it makes that much difference unless you're fishing specific pcs of structure and you don't get him in them.
