I much prefer earlies! Getting up at 4am isn't a problem and I spend the working day awake and get home for a sundowner and supper.
I absolutely loath lates. I'm up at 8am irrespective of when I went to bed, and by the time I'm inbound close to midnight my circadian rhythm is whispering 'sleep, sleep, I need sleep'.
But I wouldn't want to have an 'earlies only' roster. I like variety. Plus, a two sector day starting at 5pm leaves the majority of the 'working day' free.
