Most people choose a 9XL with the MM because that motor will generally pull less current (assuming you don't gear too high), and it would be easier on the ESC. An 8XL or 7XL could pull bursts well up into the 150A range. But yes, most of the time you pick a motor with a kv that will get you into the 30-35k rpm range with the voltage you are using.
