I agree! I have had mine set up on both the slim and ttm-19 and the tttm-19 is much better representation of his body in comparison to sculpt. Anyone who has this sculpt in hand knows it is a large sculpt, and calls for a body to match. My opinion is - the 19 is the way to go in terms of detail, and size. The head still sits a bit high though.
Here is mine on the 19.
