Assuming 1) you give better performance to relays, and 2) the list of relays remains public (or at least substantially knowable), and 3) it's possible to tell whether a given user is getting better performance for her circuit, then you severely reduce the user's anonymity, especially if her actions are linkable to each other over time.
