What is the best method to make visibility states?

[smallƑish]

I have few blocks with attributes, I m planning to make all in one block with different visibilities states. Should I Explode those or keep those blocks as it is. Which is the best method?

I think explode would be better,

Explode is the way to go.

You cannot edit attributes which are in a block which is nested within another block.

Be aware that attributes that are set to a non-visible visibility state are not presented to certain tools within AutoCAD.  For instance, if you have an attribute for size that is on a frozen visibility state, EATTEXT (Enhanced Attribute Extraction) will not be able to extract the attribute's tag or value pair.  Nor will it be visible to the properties palette, or AutoLISP.  So, batch edits to attribute values before and after changing visibility states can blow up your attribute values.
