watch out for 3C, i hated it. I thought I was golden w/ the unlimited legroom, until the FA walked around and kept bumping into my legs. The problem is that the aisle angles at row 3, and it makes a turn straight into the front of 3C. I had to angle my legs to the left to avoid the continous bumps. I think 3D is a much better seat. Loads of legroom (especially due to the curtain bulkheads), and none of of the hassle of 3C.

An additional problem is if you like to cross your legs (in the male way), your knee or your foot depending on which leg goes on top, creates a square to the outside far corner, and the way the aisle turns, it cuts into that square shape, and you'll have the FA bumping into you.
