How deep is the water and what temp. Is it? Are the gear guys backtrolling or drifting eggs when they get one here and there?
You might consider a floating intermediate or FIST head and an intermediate light MOW tip with or very light sinking tip to try to slow the swing down. A floating leader and lightly weighted fly might also swing deep and slow enough to get some attention depending on the run structure and depth... if you don't have to swing to keep happy try czech nymphing with an agent orange or onyx.
