Will be flying as a couple JFK -YVR on the 4-class 777 300ER (77H), business class.

Being OW Emerald, we can choose any seats in J class (the J section of the plane is completely empty at the moment except the two seats we have chosen) and have just reserved 11 D & G in the mini cabin just behind the F class. But i read that this row might possibly endure noise from the bin and traffic to and from the toilets.
So my question is: do we stick with 11 D&G or should we take the 12 D &G instead; or alternatively choose the middle seats in the main J cabin, something like 15 D&G?

Any guidance would be much appreciated.
