Well said Bleeds Off!!
Although I do find the 5 earlies a killer, I think that is more to do with having a young family at home than anything else!!
But then I can speak from ACTUALLY HAVING FLOWN A 5/3/5/4 roster!
I can also say that I am far less tired/fatiqued than I was under 6/3 and have more down time now than then!!
Cheers
ED
