Hey dd - Do you expect that pak boat will "tow" upstream any better than your hard shell model did? Jimbo   8-)

That's hard to say since I haven't done that yet, but the design seems to lend itself to proper towing.  First, unloaded, the canoe tends to have just a tad of rocker to it, which should aid in getting over obstructions.  Second, the built in tow rings (bow and stern) are just about on the mid-line.  Third, the hull will flex slightly in response to external force.  All of this seems to suggest an upstream tow should have acceptable properties.
