Those are big flies. Sometimes that's good, sometimes not. Maybe next time try some 2.5-3" flies tied on good ol' size 4 and 6 3x long streamer hooks.
Hope this helps. I use similar flies to what you're describing but I also use smaller ones. If I see a negative pattern I try to switch things up to see if success improves.
Sometimes you're just snakebit.
