I suggest the Eleven Point, starting Posted by: g2d on Jun-02-12 4:05 PM (EST)
below Greer Springs and continuing into Arkansas to get the length you might desire. Greer Springs adds enough water that I found the 11 Point negotiable in a very dry August. I would not recommend it on weekends, but it looks like you will go in mid week like I did. There are "official" campsites or you can improvise. There are several outfitters for shuttle. The Current would also have enough water, but would be busier.
