B-HXB has written a couple of excellent very well detailed Trip Reports about Cathay Pacific's First Class. You certainly won't find any better:
London to Hong Kong
Auckland to Hong Kong
Actually, now that I think of it,
tfung has written one or two as well, though I believe they're buried somewhere in archives by now.
Like you, I enjoy the anticipation derived from a good Trip Report. I'm booked to fly Cathay Pacific First Class JFK-YVR-HKG-JNB and back in September. I hope they still have First Class on the HKG-JNB route by then!
