Dave same tech here. I set off the feeder and big cats and grass carp show up. I use a cheap wlamart fly that falls about the same rate as a water soaked pellet. I catch mostly big cats, some bluegil and that is fun, but have hooked 8 or so 10-20 lb grass carp. Yet to land one but what fun on a 5 wt rod. Btw I feel they are not good to eat when larg but the smaller ones which I kill sometimes in hauling are excellent table fare. I was nervous at first about eating a "carp" but they really are good. However as said we have removed big ones from lakes and they tasted like mud.
