 You should feel your body shift slightly to the right on the backstroke and onto the left side on the forward stroke. This will allow you to make a free flowing stroke with consistent rhythm. If you try and keep your weight rock steady on longer putts, you will instinctively apply more power with your hands and wrists, resulting in a loss of speed and putter face direction. So remember, being a little shifty on longer putts will provide you with maximum control. So do your best Elvis!
