Seating

Hello
Just a quick question and I'm hoping you can help.
I'm flying with Virgin Atlantic in November to Orlando from Gatwick (so will probably be on the 747-400 Gwk).
I'm 6ft 3 and so leg room is fairly important. I've been looking at the Seat Ratings on here and the recommendation for 61/62/63/64 AC & HK are quite high.
As far as legroom go, do they have more than the rest of economy? Or would you recommend to sit in rows 25, 38 or 49 (which are exit rows)?
What are your thoughts and recommendations?
Richard
