What metamagics can Mystic Adepts take when Initiating?

This is an open question at this time. (Community Decision)

According to the Magician's Way (Street Grimoire, p 178), Mystic Adepts that follow the Magician's Way can access all non-Adept metamagics. To some, this implies that Mystic Adepts following any other way can only take metamagics from the Undecided Way and their chosen Way. To some, this merely restates what a Mystic Adept could already have.
