Thats a lot of river to cover in 3 days (35 miles). Sure you want to float that far? If you do....make sure you bring a water purifier so you can get some when you need it.
Baptist to Cedargrove is the best trout water. Most of your catch will be brown trout, mixed with an occasional rainbow, and smallmouth bass.. Terrestrials work well this time of year, caddis & tricos are possible, and bring some nymphs, buggers, sculpin & minnow patterns. Your spin fishing buds should do well early and late on spinners, jigs, and minnow crankbaits (1 trout >18" limit, bait & plastic are illegal).
Cedargrove to Akers Ferry offers fishing for stocked rainbow trout and the occasional smallmouth. Bait is legal below Cedargrove, so anything goes for the spin guys, try nymphs and buggers on your fly rod...
The Akers to Pulltite stretch doesnt really fish that well. To cold for bass to grow big, and no trout stocking. Fishing picks up a little bit between Pulltite and Round Spring though. If the river isnt crowded, I'd probably run & gun with a buzzbait, walk the dog plug, or fluke and have another rod rigged with a 4" worm or grub for a follow ups. If its crowded, plastics on the bottom. Cheers.
