So you already know you don't think PEY is worth paying for, you're absolutely convinced CX never should have introduced it--but then you not only accept a freebie upgrade into that cabin (one can decline an op-up, as I know from personal experience), you proceed to complain about the seating comfort. And that's when you're not whingeing about the inability to select seats on an op-up as we've heard in the past.

I really think you should consider switching to UA. They fly nonstop EWR-HKG and you might find their products more suitable. Or at a minimum, stop taking the op-ups if PEY only makes you unhappy.

I find the description of the difference in recline implausible. There's a pretty significant difference between 135 and 150 degrees and if it were true I'm sure we would have heard about it before.
