In terms of braking power in a straight line, the weight transfer that unweights the rear wheel makes a rear brake almost pointless.
For braking whilst turning, I believe that using dual brakes would reduce the incidence of steering twitch when dabbing the brakes, but I don't understand enough of the physics to explain it.
Go front brake only and get to the gym so you can handle whatever your bars decide to do.
