The controller working the piper (and on parts of the second post) is my favorite at KJFK. He always speaks slowly and pronounces everything carefully, especially when dealing with the non-English speaking crews, yet he never seems to have trouble fitting it all in, no matter how crazy things get. Some of the other tower controllers talk in machine-gun bursts, then have to repeat large portions of what they've said. Of course, everyone working KJFK tower is incredibly competent, I just think this guy's technique is the most efficient.
And thanks folks for both posts.
