My favorite fly to catch bass is a booby. Any color and works best around sunrise or sunset.
You get really nice surface action.
Make sure to squash the barb and carry long nose pliers because it helps safely releasing the fish. The tend to swallow the flies deep.
For sinking flies use darker colors with a bit of flash ans some hackle to push water.
This works better for the rest of the day. Have fun!!!
I have found these fancy bass flies to no work as good. Maybe its just me...
