Ok... A little counter productive to my argument, but... I use to do this a thing that was basically false casting, but allowing the fly to just touch the surface of the water. Three out of four times I could pull it off where the fly would touch the water a few times before I would lay it down. This trick never worked on trout, but I caught a lot of blue gill using this trick. They would run, sometimes several at a time to see what was going on. Then the fly would land and BAM! The biggest one would grab it. Since it didn't work on trout I haven't tried it since the last time I fished blue gills. Which is probably fifteen years ago. A very worthy fly rod fish in Ca. Not so much here in Wa.
