If you were on a 747 I would say definitely go to PE. On a 777-200 I personally think it's worth it. I've flown PE on both.

I haven't flown PE on the 777-300, but from the comments on FT I don't think I will, as the product appears to be a step backwards as far as comfort (legroom) goes.

I'm 6'2" as well, so I have some empathy with Mr Kellie16.
