Back in the 80s I remember flying GOD in Nationals at Waikerie where we started as soon as we could and finished most days at dusk just squeezing home over the fence.........long time since I have flown those kind of tasks.........once you cruise all day above 80 give me a ASW 20...........it's the combination of tasking and the polar envelope you are using that has changed.......IMHO........
