I have a website which will have 7 different categories. Each category has between 1-60 terms underneath it. Should I make 7 vocabularies then or make only one which has a hierarchal structure underneath it with the 7 parents with their terms underneath?

I'm trying to save some space on the content type form since I don't want 7 drop down menus everywhere. Ideally, I'd like to have an autocomplete box which has a controlled vocabulary...
