Hi recommendations for biz class on the 777200LR, 2x2x2 cabin needed please!

I'm travelling solo, I do tend to get up every now and then, it is an afternoon flight as well so I won't be sleeping, so I'm thinking of an aisle seat. The following are available: 1J, 4B, 5E, 6B, 6E, 6F, 6J, 7E, 7F, 7J.

Is there extra room in row 1, so my neighbour in 1K will easily be able to walk out of their seat? Row 7 is right in front of the economy cabin so other than getting a few wanderers from behind, is it an ok row? I've heard the social bar may disturb a bit...

Thanks people!
