TTM-19 is too big for Rick (who is tall, but pretty slim) and the Lee is too short and overly ripped.
I think the most common idea (at one time) was to use the Lee body, but modify the torso to be a bit taller. Pete Skywalker did a great custom body for his Rick that I believe combined a couple of HT bodies; it's probably the figures with the nicest looking proportions I've seen.
I think the best stock body for Rick is the Blitzway body (Scarface or Carlito). It's a tall body, but with a slim semi-muscular design.
