Is a "brown pellet looking thing" a fly, or a pellet? I think the name you're looking for is "Purina?"
Actually around here they have a fly for everything and they have a fly (artifical) that emulates a pellet. Power bait makes a brown pellet as well. And at Shady lakes here you can buy the actual pellets they feed the trout with. Kind of like how desperate are you catch a fish?
I have found over the years that a black rooster tail works, a black jig works. Depending I use olive, brown or black on the jigs. Not working I try salmon eggs, power bait or a worm.
