All questions refer to the 772...
First of all, correct me if I'm wrong, but I'm assuming that 32A and 32L are the same (just mirror seats) and the same goes for 32C and 32J?
Next, I have a choice between 32J and 32L. Which is better? To expound on myself, I prefer ideally a window seat because I like looking out the window and leaning on it to sleep. However, because I don't like climbing over people, and I like to get up and stretch a bit on long flights, I take the aisle instead. For 32L, is there a decent window, or do I have to strain to look out? Is legroom impeded by the door? Is it comfortable to lean (or at least as comfortable as any standard window seat)?

Thanks!
