Your route 2 estimate of 1.89km portgaging is probably correct - I went from White Trout to Tom Thompson last September and Kooy Pond was just stinking black muck. I poled part, then wised up and portaged the rest. Other than a short little climb out of Kooy Pond I don't recall anything difficult about the portages. Haven't done your route 1 so I'll let others comment on it.
