I am not a big guy, only about 178cm and and 80kg, so I am not as worried about leg room as what I read did not sound too bad. I am also cheap and did not want to pay the additional above what I was already paying for my seats to get legroom seats only to have to deal with noisy congregating folks. What a good strategy might be is to lock in 46/47 now and then if you decide to move up later you could, fully understanding the extra legroom spots might fill up. I am not flying till June but I check in to all four legs of the trip and see what is filling up around me and move around to keep some space. Hoping the flights will not fill up, very empty now, but they may.
