I need a peace of advice about Dimensions NAV 2013

Hi there,
I'm dealing with the upgrade of my vertical solution from Nav 2009 to Nav 2013. [-o< [-o< [-o< [-o<

As you know dimensions have change a lot, from my point of view in a very good way.
In my vertical solution I created some extra tables with the same structure that Document Dimensions and Post Document Dimension, just for storing my vertical dimensions and posting all my stuff (Creating records in table 81 with my dimension and posting them). Then, I'm not sure if I should get rid of these extra tables in order to keep all dimension, including the dimensions of my verticual solution, in the table 480.

What do you reckon??? How do you see it???
Thanks!!!
