I am a great fan of the SAA type flat seats. They are really wide and more comfortable than the herringbone.
The last few times I flew herringbone on 9W, the impression I got was that the seats were wider than the equivalent seats on AC, and therefore the foot rest was somewhat ill-aligned at the bottom
On another topic, is 9W still handing out sleeper suits in J on the YYZ-DEL route?
