P.s how is the hard trail on days 2, 3, and 4?
2. Daisy to Chickenbone West 7.9
3. Chickenbone West to Hacket Lake 7.9
4. Hacket Lake to Desor South 8.1
Day 2: There is a bit of climb out of Daisy, but not bad. Once up on the ridge it's pretty smooth sailing for the hike, with only one or two places that you have a decent up/down, from what memory serves.
Day 3: (Hatchet Lake, BTW) -You have two climbs early on. One, the climb out of West Chickenbone back to the Greenstone. The second starts about 3/4 mile from there, and is a puff up the Greenstone. However, once you're up on the ridge crest, it's a pretty decent hike, with lots of open views.
Day 4: Other than the climb out of Hatchet, this is a pretty easy section, IMHO. The ups and downs are limited, and trail is easy on the feet.
Going that direction, you COULD skip Island Mine if you wanted to, and shave a day. Two years ago, my 11 year old niece did that with us. (No pressure.)

Most of the stretch from Island Mine to Washington Creek/Windigo is a soft dirt trail, and in general is a light decline. It's pretty easy on the body.
As Danha1en notes, when camping at water, you typically need to hike 'up' first thing in the morning. Another important tidbit of IR geography: Because of how the land was formed, slopes on the N side of ridges (technically NW) are steep and acute, whereas slopes on the S/SE tend to be gentle. So, camps on the N side of trails (Many on the Greenstone; Lane Cove, etc) have pretty good hikes in and out. Others, on the South (Ritchie, Island Mine, Threemile, etc) tend to be not as harsh. Also, as the Greenstone is the dominate ridge, and water flows off of it, it doesn't go up and down as much. The Minong is more difficult in part because you're needing to climb up and down at each of the points water has eroded an escape path to the big lake.
Both are great trails, with the Greenstone being (I think) quite a bit easier. While the camps are not on Superior, the interior lakes they are on are quite nice in themselves. (Island Mine excluded.)
