The Captain gets what he wants and the Relief Commander has to fit in.
The operating FO gets what he wants and the SO has to fit in.
( they don't have to do the same rest cycle )
After all the Relief crew are exactly that, RELIEF for the operating crew.
As long as the Captain and operating FO let their counterparts know beforehand then I see no problems.
Surely there must be a usual pattern of rest/work known to most crews on certain patterns by now???
Nothing stopping you emailing or calling the Captain and asking.......
As for W commuters?? It doesn't come into my consideration, all crew members are responsible to turn up for work adequately rested...so if they are a little more fatigued then its their problem and should not disadvantage other crew rest.....
In other words, if you can't handle W patterns then DON'T DO THEM.
