Great analysis. For the trout below the weed bed i would add a smaller unweighted dropper behind the lead nymph(probably a midge larva).
Everybody loves a good feeding riffle which can be multiple trout if luck runs with you.
The deep flat is by far the toughest,and while the shot at the biggest fish is always tempting i agree hooking a good fish in this setting is a success.

The slow even water shown in the photos indicate this stream is the definition of tough. a stream to fall in love with and enjoy unlocking its mysteries.
