If I am using a pusher style fly I like to put a string of shot in front of it. For example, go 6 in and put one small one. From there go another 6-10 in and put another, slightly larger shot. I have had great success doing this. One thing to remember, as fall progresses the water is usually low and clear. The trout will be ultra aggressive. So do not rule out the fact that the trout will be inclined to take wets and pushers presented near the surface. For my leader I use the Humphries wet fly leader. I use the same dimentions but I use MUCH heavier leader materials and taper it down to 0X. No need for light leaders.
