I've only done the Mudro route a couple of times.  As a solo with kayak and with lots of small packs that need to be stowed in a larger one for portaging it is SLOW for me.  Several short portages on the route.   Took me all day to get to lower Basswood Falls and there can be additional canoe party traffic that slows you down too.  I have come in on the Fall lake route and gotten to Upper Basswood Falls in one day.  With a tow to Prairie Portage you can probably also make UBF in one day, it would be an all paddling day.  Good campsites near Upper Basswood Falls.
