Nothing wrong with 6 as a backbone for it does go the correct direction but it would be a shame not to weave up and down a bit in the prime riding areas.
That trek getting back west from the east coast is always problematic.
Nothing worse than riding into the sun coming west on the 401 after a tiring day.
That's one reason I suggested perhaps going north above Montreal but that would add a day or two to that section.
But dropping back down to the states is okay - that said - nothing much in New York near Lake Ontario and you go a bit out of your way getting home.
