Design tables or individual files ?

we are debating the advantages of design tables overusingindividual part files.  What prompted this debate wereseveralwe have encountered with configurations in design tables.Forexample:

-when opening assy's SW sometimes cannot find therightconfiguration (i.e. it sometimes will use the 'last saved')
-searching for configurations  is not as straightforward
- we have run into  cases where we have duplicate partsindesign tables and individual parts  

I would like to post this on this group to see if you hadsimilardiscussions and if you think design  tables orindividualpart-files were 'the way to go' for consumable hardwaresuch asscrews and washers ? 

Thanks for your input.
