I only took the #8 with some big ugly "unnamed" Streamers, you know the kind, if I showed you I'd have to kill you twice. Sight fished to a couple of trout, one was wading distance from Farris Creek Bridge, 24" + fish, it and none of the others were in a feeding mood, we ran out of fish I'd say a mile below the bridge, saw more rough fish than I'm use to seeing.
But the water was 67 degrees at Old Dam Ford.
