Well I'm a lot older than I look
Not one 777 FO I have ever flown with has ever left CX.
Infact I quite often get guys bid for the same trips to fly with me, we have a blast on the line. You my friend are missing out.
oh and LWMO is quite straight forward, as is any approach using Cx std calls and proceedures. Maybe you should check with Qf, they have different calls for different approaches. Something a Qf mate tells me is quite a pain in the ass.
