With that much time to hike you could do some realy cool stuff...How about parking at NF Rd 221 and entering the forest via Eagle creek. If you get there late Friday you could camp above deer skull falls, then pick up Saturday following the creek NE to the Sipsey river. Here's a thread on that area:
http://www.alatrails.com/...dex.php/topic,1928.0.html . That will place you on the south side of the river. Follow that to see Featherhawk falls, then ford across to follow TR209. You could follow Bee Branch and see Big Tree, then backtrack to TR209 and continue west to see many caves and other pois. Then maybe ford the Sipsey again, (back to the south side) to follow White Creek and see some amazing waterfalls. All about White Creek:

Then you could follow that back out to Cranal Road, loop via Little Ugly, or follow TR202 back to the Sipsey River and loop back out on the trail you came in.
