As for the OHBH return I use the same grip for the backhand and forehand so I wait to return with that grip. If I need to slice the return I change to Continental. Unless I get a slow serve I almost always take the loop out of the backhand return. I turn my upper body draw my arm back and try and meet the ball out front with an extended arm and firm wrist. I find you can get good depth and directional control with that type of abbreviated backhand return.
