Airdancer - the state of 'some' rosters have improved as pilots have approached yearly maximums and they have to be given less flying.
You case is also specific. You like ULRs hence your rosters are good. Not the case for everyone especially those who do not like ULR flying. If you are doing 90 hours plus every month it is going to grind.
I like the ULRs for the same reason you do. Some months though you simply won't get any!
Good luck swapping. I do a lot of swapping (trying) but find that unless you are swapping exact days it is almost impossible. Or I swap a period of 10 days to make it work. Both of you in OT - swap denied!
