Interesting report, thanks for posting! The new WTP seat doesn't look too bad, although not as good in appearance as QF PE. The food/service is definitely below QF standards, and presumably CX too although I haven't read one of their PE reports yet.

I agree with you that WTP is an excellent class only for upgrading with Avios to CW. If I were actually paying to travel in WTP, I'd probably think again.
