I'd say LGA 31. Sitting on the left, I'm fine flying it, but letting a new FO, whose also sitting on the right making that blind left turn is a little nerve wracking. It's also hard to judge at what altitude to shoot for while making the turn. Our virtual glide path wasn't very good at that point. Awesome approach and I loved doing it though.

I'd also say looking for your "landing partner" in SFO is a hair raiser too. Finally you spot him and gently ease up next to them. I'll say looking at YouTube comments on this approach is a fun read though.
