I completely agree. CW is better for sleeping as you don't get the chinking of plates and cutlery throughout the night, or the feeling that you are missing out on some part of the F experience. CW is more regimented which tends to be what you need for better sleep. I've twice had flights in F from JFK which have been very noisy and I would much rather have been in CW for those.

I have also got my sleeping position perfected now in CW which works pretty well for me, but at 6' 3" I have to get perfectly into that position!
