Master Angler,
Been reading all under WCPP here today.  I did a six day solo from Leano and looped North and West to Mexican Hat, to Nutria and then South down to Paull and Back to Leano.  I have BAD KNEE two surguries for Minisucus and NO ACL on Right Leg.  I am 5' 9" and am almost 54 years old and weigh 220 (overweight)  I took a 50 pound pack gear and such, a 20 lb pack (food with two bear vaults in it) a thwart bag 3 lbs and the canoe, paddles etc.  I double portaged everything and sometimes triple portaged the short stuff.  I took the topo maps, the park map (which I acutally blew up my route at office max to twice the size of original) and compass and Garmin 400 GPS Topo.  This was my first solo ever, and with patience, all will be well.  Take it at YOUR pace and watch your steps and all will be fine.
Denton Doc and Jimbo and Martin all helped me with various aspects and hats off to those fella's.
I did get a new solo canoe a couple weeks ago a Bell RockStar in Kevlight.  Can't wait to try it out on a true solo.  Took it to the lake when it was 29 degrees out just had to try it out before I put it into hibernation.  Blessings on your planning and trip and health.
