I am currently subscribed to several MT podcast feeds via iTunes (Members, Premium Members, Enhanced, Basic, etc.) and some of the podcast shows are duplicated across the various feeds.

Because of my various membership levels, should I stop one or more of these feeds? If so, how do I determine which ones to continue or stop?

 I anticipate retaining the Basic and Interviewing feeds because the appear to be somewhat static and I want to use them as refresher courses from time to time.
