you can pick up this MFS dvd too and see if the top section is something you want to deal with or not. they run off the top at ~1.74 ft in the dvd.
Middle Fork of the Salmon River DVD
i've done it at ~1.6 from indian creek in a medium loaded 16fter. boney but i enjoyed it. seemed like after 10-15 miles below indian it picked up enough that it wasn't too bad. It seems like the first upper 25 miles at low water is about knowing the lines and willingness to run over some rocks.
if you go off the top do the full 8 days for sure. river is moving allot slower so the extra mileage cuts into side hikes,ect.
