Thiws is another pass with the extra weight maps.  This time I just did a simple pass with the brush with fall off a taking in a couple of the side vertexes.  Again this is not perfect but it was done in about 15 minutes.  Whit more skill and time I could get to be like your curvy tiers.  Again this is a demo piece of what can be done.  And I did not change the constraint values to fine tune.
