Frustrates with having wasted so much time, I ended up moving upstream where I caught a couple brookies chucking streamers, which immediately improved my mood. While I was happy to get onto some fish, I was determined to get some on nymphs to field test the new leader.
As I continued upstream, I got into some more fallfish nymphing some pocket water. While they weren't what I was looking, they did help me fine tune my approach with a new leader (where to put my indicator, how long the tippet should be, etc.). Eventually, I reached a nice run where I nymphed up two more trout including a decent rainbow, a brookie, and a few fallfish. The fallfish and brookie hit the nymph as I lifted up to cast, which goes to show, the drift isn't over till it's over. The brookie was actually a fairly interesting catch since it was smaller than the previous 2 brookies, fairly dark in color, and contained some blue ringed halos that the first two fish lacked. At first, I thought it was a native but I was disappointed to see that it had slightly beat up fins (no pics unfortunately). I've heard that this freestone does contain natives in upstream sections so it gives me a little hope but the fact that I haven't caught any 2 in. brookies in this particular section pretty much dashed my hope.
