Personally, I find these guys much tougher than spring fish. You basically always have to feed the Big C fish the fly, but in late summer, you really need to feed em. The good news, lots of sun, good visuals. The bad news...weedbeds. Bottom line...the Hybrid still crushes!
Gravel fish are the best...and toughest.
My quest for 20 fish over 20 lbs might fall short for the second year in a row. 19 last year, stuck at 18 right now (though like an idiot, I didn't actually weigh a fish that was pretty clearly 20 lbs when fishing with Dan Frasier and Travis Hammond. Just held it up and dumped it back in the river like a bass. DUMB!). You can feel the cold weather approaching, and the bigger fish are starting to enter the shallows less and less...combine that with a lack of fishing time as the season winds down and it doesn't look good.
I might have to start slumming with salmon and steelhead soon.
