This is good advice. Wet flies are worth having and swinging.I would really add some wet flies. Some soft hackle that looks like a grannom. I also favor size 16-18 frenchie when I am having a tough time trying to entice the trout. It’s probably more the size than anything. Penns is full of large bugs and people often match that by throwing mops and pat’s rubber legs. Offering something in size 18 can really provide a stark contrast. I have a hard time wanting to do it on such a large stream but you will need them for any slower moving sections you may fish.
