Ryan,
I personally use application variables.
I would not use method 1 as its best practice to tell CF what type of
variables to use, other wise it has to search the variables scope to find
them. The other problem with this method is you might use one of these
variables as a local variable in the page and cause some interesting
problems.
Method 2 sill work just as well as method 3.
I have come across some web hosting companies that don't allow application
variables, so this might effect your choice.
