Some Weight In The Back?

It can be easy to pick up a knot or two with an aft CG, but stability may suffer. Be sure to consider fuel burn and plot the expected CG at the end of the flight, too.

You shouldn’t have gotten through private pilot ground school without understanding that, for the same power and weight, minimizing drag will result in an increased airspeed. A gross example might be the difference in airspeed with flaps extended at, say, 55-percent power and when they’re retracted. Of course, no one cruises with flaps extended, but you may inadvertently be adding to the airplane’s total drag in cruise when you load it.
