I managed to upgrade SFO-LAX-NRT-PEK (73A on a 747 and 1C on a 333) using miles, but coming back I'm stuck in Y on a 332

I've never had the "pleasure" of flying a 332 - always a 333. On Seatguru it looks rather sad... assuming that all I care about is legroom, am I better off in 11C or 29B? I'm hoping that it opens up, but right now it's zeroed out. J0/C0 and no waiting list. Looks like I will likely be stuck in Y, and as the seats for my return segment open up Sunday night I'm trying to figure out which I want... suggestions?
