I've done a bit of searching, but couldn't find really strong descriptions of the old long haul J that is now being updated by the "controversial" new J.

I've flown the new J on a recent flight from NRT-HKG, and the short haul "old old school" J many times on short haul flights (TPE-HKG, etc...). I didn't mind the new J at all. I thought it was pretty good. I was in row 88 on the upper deck of a 747, would that be the 74A? - I'm still learning all the equipment codes for CX.

If I fly on the SFO-HKG or other west coast flights to HKG, I know the chances are getting better for the new J, but if I get the old J, how bad is it? Is it bad at all?

Am I correct in assuming it's basically an angled, almost lie flat product? That is what I've flown many times on Eva and it was fine for me.

Thanks for your help and apologies if it is a redundant question.
