The MOST important thing in a heavy jet is to have your velocity vector straight down the runway at touchdown. Then inertia will tend to keep you tracking straight as you use the controls to keep the wings level. The 747 will align itself on touchdown if landed in a crab. For a slip, the max bank angle before a pod strike is about 8 degrees, so any more than 5 deg of bank is asking for trouble.
I use a crab until just before the flare. Then I start feeding in rudder and aileron to reduce the crab angle at touchdown and "preprogram" the ailerons into the wind. After that, fly the airplane until it's stopped.
