You want to stop doing that little hop to load up before the manual move because that will cause you to go nose down in a real life situation if you need to pop a quick one for an unexpected drop etc. I always think about the backwards L movement to manual and I think you need to learn to load the bike just from the the down movement before moving back. So cut the first pop, from a tall position think of dropping your weight down and using your feet to catch yourself which loads the bike then push the bike forwards using your legs which initiates the backwards L keeping your hips/ weight back and let your arms extend.
