Seems like there are numerous jig head designs for different applications. I am so confused.

1.Football head, casting, standard, flipping, arky

Can someone clarify as to which is used for what and when?

Can you interchange them?

Does/can one type excel at all applications/situations better than the others?

Thanks

There are a lot of opinions out there ..here is an informative article by a well renowned Western jig fisherman
