I certainly didn't find it an improvement. 45 minutes of my knees rubbing against the seat in front between NCL and LHR was enough to put me off. From now on I will travel in ET and book emergency exit seats.

I appreciate people will have differing views in this but the loss of seat pitch cannot be described as a "huge improvement", especially if you're tall enough for it to make that crucial difference between knees rubbing or not.
