Thanks all for the good discussion. All the points mentioned are valid (especially the caution about LNKLST UPDATE).
I don't think there is all that much complexity involved with using dynamic LNKLST. But its true effectiveness is when you don't have a requirement that old jobs use the new information (because then you don't need LNKLST UPDATE)..
