My preference for seating is:
LHS, RHS, bunk!
Seriously, J class and Upper Class Suite are excellent but not rows 2-5 - too close to the loo at the front and not at the back of the cabin - too close to the bar (unless you plan to spend all night there!) - try for rows 8-12 if you can. Long way to go in W class and I hope that your business doesn't consider Economy as an option.
Expect that it will be pretty full on a Fri evening.
Enjoy the flight.
