Here are a number of charts that can help you with disc selection. Be sure and read the information in the margins.

Premium plastic (champion, star, esp, z, etc.) takes longer to break in, so it remains more stable, which makes it better in a headwind, but maybe too stable for calm weather or tailwind. Base plastic (dx, x, pro, etc.) breaks in more quickly, so a disc mold that starts out too stable will more quickly become less stable and fly straighter, but then also start turning over before long. It's a tradeoff. Most people prfer premium plastic in their drivers, and base plastic in putters. For mids, I like more stable mids to be in premium plastic so they will retain that stability. For less stable mids, I prefer to get somewhat stable mids in base plastic and break them in, because I like the stiffness of the base plastic.
Here is an article on windplay that will help you figure out how to use the right disc at the right time.
