I see so many discussions about why Innova is so successful/widespread, and most of them miss on a key point - The disc rating system. Innova's seemingly simple method of rating their discs makes a lot more sense to most new players and, without proper guidance otherwise, it's quite easy to assume you can fix any and all problems by getting a disc that is rated better for you. Other manufacturers use either a much more vague (and therefore more realistic) system (Discraft for example) or they simply use Innova's system (like Lat 64 does with most of their discs). Innova appeals to beginners because it is easier to understand, and once someone commits to a system, it can be difficult to switch to something else, especially if you can't tell what a particular disc is supposed to do.
