SS I think thats a pretty good wrap on commuting - not a long term option for many.
The dynamics and rostering practises may change a bit over the next 12 months as the current rumour is 100 new FO's this year.
I take that to mean a good number of commands as well so all in all I would think the rosters of our current FO's this year should have significant numbers of days off to allow for the new FO's to be trained and to allow the RHS Training Captains to do their jobs for the Command upgrades.
