Question about rasp

I am looking at buying this set of rasp I was thinking of the fine and course set. Do I need the mediums as well? How are they? Comments? I will be using them for typical shaping for smaller type projects like tool plane/saw/chisel handle replacements maybe some making the occasional plane and that sort of projects.
