Howie - I guess I should scroll down more often to check the older messages... oh well, I'm only 3 months late in replying
Since we had 11 days for the trip, we really took our time... lots of fishing and photographing along the way. So expect you would be ok making to Knife in one day. Although the 200-ish portages into and out of Vera really wore us down... it was nice to break them up. Don't tell anyone, but early in the trip we were triple portaging! I can partially blame excessive camera gear, but being a bit out of shape probably contributed too.
