we use the xref title block. We often have revision notes that need to update on all sheets and the xref'd title block works great for this. also if a sheet is added and we now have 20 sheets instead of 19 we just open the title block for that set of drawings change 19 to 20 and save and it's updated to all the sheets. now if there was just a way to have it update to the already plotted plts or pfs that would be awesome

We speciify template .dwt files for our title blocks. The template file has an xref for the linework, blocks for the logos, etc and an attribute block for title block text.
We have had several complete changes to title block content and layout over the years, and used numerous lisp routines to allow updating of the xref, changing logos and updating/moving attribute information so all drawings look the same.
Being an xref means we can also copy that file to the specific project directory, and make title block changes that apply only to that project, like adding client logos and information.
