If you are planning 5 days to Pittsburgh landing you are going to have some short river days and/or 2 layover days. Map online read panes bottom to top: https://www.fs.usda.gov/detailfull/w...570&width=full
Here is my 2 cents, YMMV.
Day 1 - launch and camp, take a couple of oar strokes, and camp at either Warm Springs, Battle Creek, or Wild Sheep camp (and psych yourself out looking at the rapid all evening). total miles 2-4
Day 2 Run Wild sheep and Granite, take a peak in the Green Room (or run through it if flows are around 25k cfs) scout both if no-one on the trip has done 'em. Now make a decision, camp 1 night at Oregon Hole or Saddle creek, or also run the Bernards and waterspout. Then hope like Heck it is a non-motorized week and you have a shot at Pine Bar for a layover day (at any rate stop and jump off sturgeon Rock). If Pine bar is taken, go for a single day at Upper Quartz. miles 7 to Saddle Creek, 15 to Pine Bar.
Day 3/4 Run to Kirkwood Ranch. For sure layover spot. You have 4-5 camps and a flush toilet, museum, hiking up to the mansion, good fishing and swimming...just do it.
Day 4/5 whichever day you leave Kirkwood, either run out to Pittsburgh, or Stop at Corral Creek or Fish Trap Bar and have a 2 mile run-out the next day.
Just a word to the wise concerning critters you might not be used to coming from Tennessee. If anyone on the trip has a major spider phobia, have them stay out of the blackberry bushes. There are going to be rattlesnakes, just get used to that idea. Lastly, you are probably going to see black bears. Keep your food secured and some bear spray in camp... I have seen bears every single trip I have done on hells canyon (double digits) and never had an issue with one...rattlesnakes are a different story, but I digress.
Edit #3. Fishing.... The smallmouth bass fishing is going to be somewhere in the area between good and freaking unearthly. Tube baits, crawdad pattern grubs, crankbaits, just about freaking anything will work. It will be hard to catch anything else. There are sturgeon down there, read the regs though, catch and release only.
Edit #4 Its gonna be hot...but its a dry heat
