So I understand that this Dec., LH 471 yyz-fra will have the new business class layout, which is NOT the V arrangement, but where the seats are parallel to each other instead. While I am partial to the upper deck, anyone flown this configuration and know which window seat had the most space to step out with minimal impact to my seatmate (a stranger, as I'll be travelling alone)?

I know there are a few variants of this new 747-400 layout (without first class). According to LH's web site, my particular flight, as of now, is:

2-2 (4 rows) or 2-3-2 (4 rows) on lower deck, and 2-2 (5/6 rows) on upper deck.

Are they essentially all the same?
