I think it works for me because if I start driving up early, I can be on Moose at 3 or 4 with a stop at Zups and CCO.  And, if it is poor weather, I can probably still bunkhouse and take a tow in the morning.  I use CCO, which has a small store at their Moose base for teh very last minute items. What I haven't done but have thought about is taking a tow the later afternoon/early evening before Q rather than paddle.  I guess when I've done this Moose was beautiful for paddling.  It's about 2 hours tandem on a glass lake day for me - under 8 miles.
