Never hunted that far north, I can only base my selection on my own experience. I prefer to hit the early part of the rut, not too early, but just before it opens wide open. The bucks are moving more, the does are ready just yet and thus it really frustrates the bucks and they move more. I chose the second week of Novfor that fact. Lots of deer movement, focusing on main travel corridors between food and bedding for those cruising bucks.
